Exhibit 10.84

DEFAULT WAIVER AND CONSENT

PURSUANT TO

LOAN AND SECURITY AGREEMENT

This DEFAULT WAIVER AND CONSENT Pursuant to Loan and Security Agreement (this “Consent”) is entered into this 31st day of October, 2012, by and between SILICON VALLEY BANK (“Bank”) and RAMTRON INTERNATIONAL CORPORATION, a Delaware corporation (“Borrower”), whose address is 1850 Ramtron Drive, Colorado Springs, Colorado 80921.

RECITALS

A. Bank and Borrower have entered into that certain Amended and Restated Loan and Security Agreement dated as of February 29, 2012 (as the same may from time to time be amended, modified, supplemented or restated, the “Loan Agreement”). Bank has extended credit to Borrower for the purposes permitted in the Loan Agreement.

B. Bank and Borrower have determined that Borrower failed to comply with the EBITDA covenant set forth in Section 6.9(b) of the Loan Agreement for the month of September of 2012 (the “Existing Default”) and will fail to comply with such EBITDA covenant for the month of October of 2012 (the “Potential Default” and with the Existing Default, the “Defaults”).

C. Borrower has requested that Bank waive its rights and remedies against Borrower, limited specifically to the Defaults. Although Bank is under no obligation to do so, Bank is willing to not exercise its rights and remedies against Borrower related to the Defaults on the terms and conditions set forth in this Consent, so long as Borrower complies with the terms, covenants and conditions set forth in this Consent.

D. Borrower has further requested that Bank consent to the stock purchase of Borrower by Cypress Semiconductor Corporation and the resulting change of control of Borrower (the “Change of Control Transaction”). Bank has agreed to so consent, but only to the extent, in accordance with the terms, subject to the conditions and in reliance upon the representations and warranties set forth below.

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing recitals and other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, and intending to be legally bound, the parties hereto agree as follows:

1. Definitions. Capitalized terms used but not defined in this Consent shall have the meanings given to them in the Loan Agreement.

2. Waiver of Covenant Default. As of and from the time of their occurrence, Bank hereby waives Borrower’s Defaults under the Loan Agreement by virtue of Borrower’s failure to comply with the EBITDA requirement set forth in Section 6.9(b) of the Loan Agreement as of September 30, 2012 and estimated to occur as of October 31, 2012. Bank’s waiver of Borrower’s

compliance of this covenant shall apply only to the foregoing periods. Accordingly, for all periods except that set forth above and at all times hereinafter, Borrower shall be in compliance with this covenant.

Bank’s agreement to waive the above-described defaults (1) in no way shall be deemed an agreement by the Bank to waive Borrower’s compliance with the above-described covenant as of all other dates and (2) shall not limit or impair the Bank’s right to demand strict performance of this covenant as of all other dates and (3) shall not limit or impair the Bank’s right to demand strict performance of all other covenants as of any date.

3. Consent to Change of Control Transaction.

3.1 Consent. Notwithstanding any other provision of the Loan Agreement, the Bank hereby consents to the Change of Control Transaction; provided, however, that upon the closing of the Change of Control Transaction, the Loan Agreement and all related Loan Documents shall be immediately terminated (except for any provisions that survive in accordance with their terms) and all Obligations shall be immediately payable (or with respect to any outstanding Letters of Credit, cash secured in accordance with the terms of the Loan Documents and such Letters of Credit).

4. Limitation of Agreement.

4.1 The provisions set forth in this Consent, above, are effective for the purposes set forth herein and shall be limited precisely as written and shall not be deemed to (a) be a consent to any amendment, waiver or modification of any other term or condition of any Loan Document, or (b) otherwise prejudice any right or remedy which Bank may now have or may have in the future under or in connection with any Loan Document.

5.7 This Consent has been duly executed and delivered by Borrower and is the binding obligation of Borrower, enforceable against Borrower in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, liquidation, moratorium or other similar laws of general application and equitable principles relating to or affecting creditors’ rights.

6. Prior Agreement. Except as expressly provided for in this Consent, the Loan Documents are hereby ratified and reaffirmed and shall remain in full force and effect.
