EXHIBIT 1 --------- TOWER SEMICONDUCTOR JOINS ARM FOUNDRY PROGRAM MIDGAL HAEMEK, ISRAEL AND CAMBRIDGE, UK - NOV. 13, 2002 - Tower Semiconductor (NASDAQ: TSEM; TASE: TOWER) and ARM [(LSE: ARM); (NASDAQ: ARMHY)], the industry's leading provider of 16/32-bit embedded RISC processor technology, today announced that Tower has joined the ARM Foundry Program. Through the Program, Tower will gain access to two of ARM's most widely used embedded microprocessor cores, enabling Tower to produce customers' ARM(R) core-based products in its Fab 2 facility. ARM will port its industry-leading ARM7TDMI(R) core and ARM922T(TM) core to Tower's standard-logic 0.18-micron process technology. Tower will make both cores available to customers by the first quarter of 2003. "Establishing a relationship with one of the world's top IP providers certainly boosts our efforts to create a comprehensive, state-of-the-art IP portfolio for our Fab 2 facility," said Sergio Kusevitzky, senior director of IP and Design Services, Tower. "The availability of the ARM cores is part of our strategy to widen the IP portfolio. Not only do we want to give new and existing fabless customers more design options, but we are also committed to helping them shorten design cycles and accelerate time-to-market. This agreement is proof of our intention and gives our customers the confidence and the ability to achieve those goals." "Tower's willingness to work closely with ARM Partners will prove to be a great asset to our Foundry Program," said Bruce Beckloff, director, European Marketing, ARM. "With their strong focus on engineering excellence, Tower will enable fabless semiconductor companies as well as IDMs to realize their ARM Powered(R) designs in silicon with strong results in terms of both quality and yield." As part of the agreement, ARM will validate cores built on Tower's 0.18-micron process to provide silicon proven IP. The ARM7TDMI core, a 32-bit embedded RISC processor delivered as a hard macrocell, enables system designers to build embedded devices requiring small size, lower power and high performance. Applications include personal digital assistants (PDAs), digital still cameras and pagers. Based on the high-performance ARM9TDMI(TM) 32-bit RISC CPU, the ARM922T core can serve as a platform for a wide variety of operating-system-based devices, next-generation smart phones and 3G-baseband and applications processors. ABOUT THE ARM FOUNDRY PROGRAM The ARM Foundry Program is an innovative business model that enables fabless semiconductor companies in emerging markets to gain access to ARM processor technology for use in the design and manufacture of advanced system-on-chip (SoC) solutions. There are currently 48 Partners in the Foundry Program, which was launched in 2000. ARM now offers the ARM7TDMI core, the ARM922T core, the ARM946E(TM) core and the ARM1022E(TM) core through the Program. The Foundry Program offers a flexible partnership model that accelerates the time-to-market for ARM core-based designs and enables OEMs, which do not have access to fabrication facilities, to work directly with an approved ARM semiconductor foundry. Unlike a traditional ARM license, where a licensee gains both manufacturing and design rights, the ARM Foundry Program builds a three-way Partnership between ARM, an approved silicon foundry, and an OEM. 4
