RAMTRON REPORTS SECOND QUARTER 2012

FINANCIAL RESULTS

COLORADO SPRINGS, CO—July 24, 2012 — U.S. semiconductor maker Ramtron International Corporation (Nasdaq: RMTR), a leading developer and supplier of ferroelectric-based memory and integrated semiconductor products, today reported total revenue of $14.2 million for the second quarter of 2012, compared to $16.8 million for the second quarter of 2011. Net income for the second quarter of 2012 was $69,000, or $0.00 per share, compared with a net loss of $683,000, or ($0.02) per share, for the second quarter of 2011.

“Distributor order flow began to slow as headwinds in the semiconductor markets that we serve picked up toward the end of the second quarter and stalled our revenue growth,” said Eric Balzer, Ramtron’s chief executive officer. “Despite this industry softness, we posted Adjusted EBITDA of $1.9 million by maintaining operational discipline and reduced inventory by approximately $1.4 million on a sequential basis.

“In addition, we gained traction with our demand creation initiatives during the quarter, logging new wins and advancing opportunities in automotive, metering and medical applications,” Balzer continued. “We are now seven months into our program of driving design wins with new and existing customers after last year’s hiatus in design activity, when our highest priority was to work with our existing customers to manage supply constraints. With a number of new design wins under our belt and emerging opportunities on the horizon, we remain well positioned for growth in 2013 and beyond.”

“Limited near-term visibility, brought on by weak industry conditions, has caused us to become more conservative on our outlook for 2012,” Balzer added. “As a result, we are operating under the assumption that revenue stays flat for the third-quarter of 2012. At this level, we are confident that we will maintain positive cash flow from operating activities. While managing the business for cash flow, we are intensely focused on driving growth through the execution of our demand creation initiatives, expanding design activity, and introducing new products so that we are prepared for an improvement in industry conditions and, longer term, to take advantage of the significant opportunities for our F-RAM based low energy, wireless, and high data integrity solutions,” Balzer concluded.

Business Outlook

In light of limited near-term visibility, Ramtron is modifying its guidance policy from providing an outlook for full-year 2012 to an outlook for the next reported quarter. As visibility and industry conditions improve, Ramtron’s management will re-evaluate its guidance policy.

The following statements are based on Ramtron’s current expectations of results for the third quarter of 2012. These statements are forward looking, and actual results may differ materially from those set forth in these statements. Ramtron intends to continue its policy of not updating forward-looking statements other than in publicly available documents, even if experience or future changes show that anticipated results or events will not be realized.

For Q3 2012:

Strategic Alternatives Review Process

Ramtron’s Board of Directors is continuing to evaluate strategic alternatives including, but not limited to, a potential sale of the Company, a strategic alignment with one or more investors or joint venture counterparties, other potential strategic transactions to realize the long-term value of the Company for its stockholders, or continuing with the Company’s current growth plans. The Board continues to believe that completing the strategic review process is one way to ensure that Ramtron stockholders have the best opportunity to realize a full and fair value for their investment. No assurance can be given as to whether this process will result in a proposed transaction, whether any transaction that may be proposed as a result of such process would be acceptable to the Company and the Board or whether any such proposed transaction will be announced or consummated.

Non-GAAP Financial Measures

This release references Adjusted EBITDA, which is not a financial measure as defined by generally accepted accounting principles (GAAP). We present Adjusted EBITDA as a supplemental measure of our performance. We define Adjusted EBITDA as net income plus interest expense, provision for taxes, depreciation and amortization, and non-cash stock based compensation expense. In evaluating Adjusted EBITDA, investors should be aware that we may incur expenses in the future that are the same as or similar to some of the adjustments in this presentation. We present Adjusted EBITDA because we believe it assists investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. In addition, our credit agreement uses Adjusted EBITDA to measure our compliance with certain covenants. Below is a reconciliation of Adjusted EBITDA to net income for the second quarter of 2012:
