FINANCIAL RESULTS

COLORADO SPRINGS, CO—October 20, 2011 — Ramtron International Corporation (Nasdaq: RMTR), a leading developer and supplier of low power nonvolatile ferroelectric random access memory (F-RAM) and integrated semiconductor products, today reported its financial results for the third quarter of 2011.

2011 Third-Quarter Financial Highlights

2011 Third-Quarter Corporate and Product Highlights

“Our supply chain team executed exceptionally well during the quarter, which allowed us to work through a significant portion of our backlog and further improve our customer deliveries,” said Eric Balzer, Ramtron’s chief executive officer. “As a result of our recent progress, we remain on track to completely resolve our supply constraints during the fourth quarter.

“With the recent hiring of highly experienced sales and marketing executives, we are positioning Ramtron to be more agile, market-driven, and customer centric, which is aimed at improving our time to market and revenue,” Balzer continued. “We believe the alignment of our improved supply chain with the strengthening of our marketing and sales organization will invigorate the rollout of our wireless memory products and support the pending introduction of the world’s most energy efficient nonvolatile memory products.”

RAMTRON REPORTS THIRD-QUARTER 2011 FINANCIAL RESULTS

The Company reported total revenue of $22.0 million for the third quarter of 2011, compared with $19.9 million for the same quarter last year. Product gross margin for the third quarter of 2011 was 51%, compared with 52% for the third quarter of 2010.

The Company reported net income of $1.2 million, or $0.04 per share, for the third quarter of 2011, compared with net income of $342,000, or $0.01 per share, for the third quarter of 2010. Third-quarter 2011 results included stock-based compensation expense of $558,000 and an income tax provision of $529,000. At September 30, 2011, the Company’s cash and cash equivalents totaled $8.2 million.

2011 Full-Year Outlook

“Given the considerable progress we have made in product deliveries, building capacity at our Texas wafer source, and our year-to-date revenue of $49.4 million, we are confident that full-year revenue of between $65 million and $70 million is achievable,” said Eric Balzer, Ramtron’s CEO. “Although we expect continued improvement in yields and lower product testing costs in the fourth quarter, we will begin to depreciate equipment on our new manufacturing line, which we expect to add approximately $400,000 to our expenses in the fourth quarter. Further, indications of weakening demand in the overall semiconductor industry have caused us to slow down the pace of investments in engineering resources. Taking these factors into account along with our current outlook for gross margin and operating expenses in the fourth quarter, we are revising our EPS forecast and now anticipate net income of $0.02 to $0.05 per share for the second half of 2011.”

“With our supply constraints rapidly moving behind us, we are intensifying our focus on creating new and innovative products that leverage our F-RAM technology advantage,” Balzer continued. “We build our products on the most advanced F-RAM manufacturing process in the world and this advantage provides an exciting opportunity for us to develop highly differentiated products that add significant value to our customers’ products.”
