To follow is Ramtron's response to the March 9, 1998 EE Times article that covered the ISIF conference. We hope that this clears up a few concerns about the information presented in the article. Thanks for your continued interest in the Company. Lee Brown Director of Communications and Investor Relations Ramtron International Coproration --------------------------------------------------------------------- Dear Craig and Yoshiko: I appreciated your recent article in the March 9, 1998 issue of EE Times titled "Ferro RAMs headed for volume debut." After reading the article, several Ramtron engineers that attended and presented at the conference noted some errors and omissions that we felt were worth mentioning. 1. Ramtron was not mentioned in the article. Ramtron is the only company to date that has shipped commercial Ferroelectric RAM (FRAM(R)) products to customers. We have been selling PZT based FRAM products ranging in densities from 4K to 64K since 1993, as well as custom RFID circuits. Since then Ramtron has delivered over 8 million parts to more than 500 customers. 2. Matsushita is not going to be first out of the gate. Given the fact that we have been in the market for 5 years, Ramtron was the first to achieve commercial status. Although our volumes in the past have not been significant, we expect to expand our FRAM shipments this year now that our foundry partner, Rohm Company Limited, is in production. We have already begun receiving production class shipments from Rohm and expect to receive more than 1.5 million units by June. 3. The article implies there are no ferro fabs besides Matsushita and Siemens. This is not true. In addition to Rohm's line, Hitachi and Fujitsu (Ramtron alliance partners) have announced 0.8 and 0.5 micron ferro lines for 256K and 64K embedded products. Both are sampling protoype silicon. 4. The article implies that SBT is the sole material capable of scaling to 500A. PZT has also been scaled to comparable SBT thicknesses resulting in excellent low voltage capabilities. 5. Ramtron's datasheets specify PZT fatigue at 1E10, not 1E7. This data has been shown at ISIF for several years. We hope that you take these comments with only the best of intentions. We are proud of the work we have accomplished to date and felt it necessary to set some of the facts straight. We would like an opportunity to send you a complete literature packet on Ramtron for your files. Please send your mailing address and we will mail a packet promptly. In addition, I would be happy to schedule an interview with any of our engineers if desired. Best regards, Lee A.
