The Company’s exposure to market risk for changes in interest rates relates primarily to its investment portfolio. The Company places its investments with high credit issuers and, by investment policy, attempts to limit the amount of credit exposure to any one issuer. As stated in the Company’s investment policy, it will ensure the safety and preservation of the Company’s invested funds by limiting default risk and market risk. The Company has no investments denominated in foreign country currencies and therefore is not subject to foreign exchange risk from these assets.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company mitigates default risk by investing in high credit quality securities and by positioning its portfolio to respond appropriately to a significant reduction in a credit rating of any investment issuer or guarantor. The portfolio includes only marketable securities with active secondary or resale markets to enable portfolio liquidity.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company's accounts receivable are derived from revenue earned from customers located in the U.S. and internationally.

CY2014	us-gaap	Description Of New Accounting Pronouncements Not Yet Adopted DescriptionOfNewAccountingPronouncementsNotYetAdopted	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Recent Accounting Pronouncements</font></div><div style="line-height:120%;padding-bottom:10px;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In November 2014, the FASB issued Accounting Standard Update ("ASU") No. 2014-17, Business Combination (Topic 805): Pushdown Accounting (a consensus of the FASB Emerging Issues Task Force). The amendments in this Update apply to the separate financial statements of an acquired entity and its subsidiaries that are a business or nonprofit activity (either public or nonpublic) upon occurrence of an event in which an acquirer (an individual or an entity) obtains control of the acquired entity. The amendments in this Update are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or its most recent change-in-control event. However, if the financial statements for the period in which the most recent change-in-control event occurred already have been issued or made available to be issued, the application of this guidance would be a change in accounting principle. The Company does not expect that this guidance will have a material impact on its financial position, results of operations or cash flows.</font></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In August 2014, the FASB issued ASU No. 2014-15, "Disclosures of Uncertainties About an Entity's Ability to Continue as a Going Concern." The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company does not expect that this guidance will have a material impact on its financial position, results of operations or cash flows.</font></div><div style="line-height:120%;padding-bottom:10px;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2014, the FASB issued ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718)," which makes amendments to the codification topic 718, "Accounting for Share-Based Payments," when the terms of an award provide that a performance target could be achieved after the requisite service period. The new accounting standards update becomes effective for the Company on January 1, 2016. The Company is currently evaluating the impact that this guidance will have on its financial position, results of operations or cash flows.</font></div><div style="line-height:120%;padding-bottom:10px;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2014, the FASB and International Accounting Standards Board issued their converged accounting standards update on revenue recognition. The core principle of the new guidance is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (that is, payment) to which the company expects to be entitled in exchange for those goods or services. The new guidance also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. The new accounting standards update becomes effective for the Company on January 1, 2017. The Company is currently evaluating the impact that this guidance will have on its financial condition and results of operations.</font></div><div style="line-height:120%;padding-bottom:10px;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The new accounting standards update becomes effective for the Company on January 1, 2015. Early adoption is permitted for new disposals (or new classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company does not expect that this guidance will have an impact on its financial position, results of operations or cash flows as the Company does not currently have discontinued operations.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In July 2013, the FASB issued ASU No. 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” ("ASU 2013-11"). ASU 2013-11 provides guidance on the presentation of unrecognized tax benefits. ASU 2013-11 requires presenting an unrecognized tax benefit or a portion of an unrecognized tax benefit as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carry forward, except to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This accounting standards update became effective for the Company on January 1, 2014 and was applied prospectively to unrecognized tax benefits that existed at the effective date with retrospective application permitted. Upon adoption of this guidance in the first quarter of 2014, the Company reclassified </font><font style="font-family:Times New Roman;font-size:10pt;color:#000000;">$4.7 million</font><font style="font-family:inherit;font-size:10pt;"> from a long-term tax liability to a reduction of a deferred tax asset.</font></div></div>

(the “Company” or “Rambus”), the innovative technology solutions company that brings invention to market, was incorporated in California in March 1990 and reincorporated in Delaware in March 1997. In addition to licensing, the Company is creating new business opportunities through offering products and services where its goal is to perpetuate strong company operating performance and long-term stockholder value. The Company generates revenue by licensing its inventions and solutions, whether in the form of patent licensing, solutions licensing, services or products, to market-leading companies.     </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:17px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">While the Company has historically focused its efforts on the development of technologies for electronics memory and chip interfaces, the Company has expanded its portfolio of inventions and solutions to address additional markets in lighting, chip and system security, as well as new areas within the semiconductor industry, such as computational sensing and imaging. The Company intends to continue its growth into new technology fields, consistent with its mission to create great value through the Company's innovations and to make those technologies available through both its licensing and non-licensing business models. Key to the Company's efforts will be hiring and retaining world-class inventors, scientists and engineers to lead the development of inventions and technology solutions for its fields of focus, and the management and business support personnel necessary to execute its plans and strategies.</font></div></div>

The Company accrues for sales returns and warranty based on experience, none of which are currently material. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Rambus generally recognizes revenue using percentage of completion or proportional performance for development contracts related to licenses of its solutions that involve significant engineering and integration services. For agreements accounted for using the percentage-of-completion method, Rambus determines progress to completion using input measures based upon contract costs incurred. Rambus has evaluated use of output measures versus input measures and has determined that its output is not sufficiently uniform with respect to cost, time and effort per unit of output to use output measures as a measure of progress to completion. </font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"></font></div></div>

The terms of the royalty agreements generally either require customers to give Rambus notification and to pay the royalties within a specified period or are based on a fixed royalty that is due within a specified period. Many of Rambus’ customers have the right to cancel their licenses. In such arrangements, revenue is only recognized to the extent that is consistent with the cancellation provisions. Cancellation provisions within such contracts generally provide for a prospective cancellation with no refund of fees already remitted by customers for products provided and payment for services rendered prior to the date of cancellation. Rambus has </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">two</font><font style="font-family:inherit;font-size:10pt;"> types of royalty revenue: (1) patent license royalties and (2) technology license royalties.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Patent licenses - Rambus licenses its broad portfolio of patented inventions to companies who use these inventions in the development and manufacture of their own products. Such licensing agreements may cover the license of part, or all, of Rambus' patent portfolio. The contractual terms of the agreements generally provide for payments over an extended period of time. For the licensing agreements with fixed royalty payments, Rambus generally recognizes revenue from these arrangements as amounts become due. For the licensing agreements with variable royalty payments which can be based on either a percentage of sales or number of units sold, Rambus earns royalties at the time that the customers’ sales occur. Rambus’ customers, however, do not report and pay royalties owed for sales in any given quarter until after the conclusion of that quarter. As Rambus is unable to estimate the customers’ sales in any given quarter to determine the royalties due to Rambus, it recognizes royalty revenues based on royalties reported by customers during the quarter and when other revenue recognition criteria are met.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In addition, Rambus may enter into certain settlements of patent infringement disputes. The amount of consideration received upon any settlement (including but not limited to past royalty payments, future royalty payments and punitive damages) is allocated to each element of the settlement based on the fair value of each element. In addition, revenues related to past royalties are recognized upon execution of the agreement by both parties, provided that the amounts are fixed or determinable, there are no significant undelivered obligations and collectability is reasonably assured. Rambus does not recognize any revenues prior to execution of the agreement since there is no reliable basis on which it can estimate the amounts for royalties related to previous periods or assess collectability. Elements that are related to royalty revenue in nature (including but not limited to past royalty payments and future royalty payments) will be recorded as royalty revenue in the consolidated statements of operations. Elements that are not related to royalty revenue in nature (including but not limited to punitive damage and settlement) will be recorded as gain from settlement which is reflected as a separate line item within the operating expenses section in the consolidated statements of operations.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Technology licenses - Rambus develops proprietary and industry-standard products that it provides to its customers under technology license agreements. These arrangements include royalties, which can be based on either a percentage of sales or number of units sold. Rambus earns royalties on such licensed products sold worldwide by its customers at the time that the customers’ sales occur. Rambus’ customers, however, do not report and pay royalties owed for sales in any given quarter until after the conclusion of that quarter. As Rambus is unable to estimate the customers’ sales in any given quarter to determine the royalties due to Rambus, it recognizes royalty revenues based on royalties reported by customers during the quarter and when other revenue recognition criteria are met. </font></div></div>
