ISSI to License Spansion HyperFlash Memory and HyperBus Interface

New Innovative Solutions to be Delivered to Automotive and Industrial Customers

MILPITAS, Calif. and SUNNYVALE, Calif., Jan. 8, 2015 -- Integrated Silicon Solution, Inc. (NASDAQ: ISSI), a leader in advanced memory solutions, and Spansion (NYSE: CODE), a global leader in embedded systems solutions, today announced a licensing agreement that provides ISSI access to Spansion's HyperFlash™ memory and HyperBus™ technology portfolio, as well as access to MirrorBit™ technology in Spansion's foundries. The agreement will expand Spansion's licensing revenue from Spansion's MirrorBit technology, HyperFlash™ memory and HyperBus™ interface licensing program. The agreement provides additional IP rights to ISSI to expand its flash product portfolio for automotive and industrial customers, as well as access to HyperBus™ technology, which dramatically improves memory performance while reducing pin count and board space. Financial terms of the agreement were not disclosed.

"This new agreement, combined with our prior cross-licensing and development agreements with Spansion, provides additional access to Spansion's flash memory products and further strengthens our collaborative partnership," said Lyn Zastrow, VP of ISSI Automotive Business Unit. "This partnership is an important step in ISSI's strategy to provide a broad portfolio of specialized flash products, further expanding the solutions available to key customers in the automotive and industrial markets we serve. Access to Spansion's revolutionary HyperBus™ Interface and MirrorBit technology will result in the development of a new class of high-performance memory products to service our automotive and industrial customers."

"Momentum is rapidly growing for Spansion's HyperBus™ and HyperFlash™ memories by chipset suppliers and OEMs globally," said Robin Jigour, senior vice president of Spansion's Flash Memory Business Group. "Our expanded partnership with ISSI will accelerate development and customer adoption of innovative products based on our HyperBus™ interface. In addition, this agreement underscores the value of our intellectual property and commitment to provide access to our IP across the industry."

ISSI intends to develop multiple HyperRAM and HyperFlash™ products based on the HyperBus™ interface. By combining HyperFlash™ and HyperRAM components on a single bus, chipset providers can reduce controller pin count, accommodate smaller packages and simplify PCB design, resulting in significant cost savings while dramatically improving performance. ISSI intends to provide the same high quality and long term support for HyperRAM and HyperFlash™ customers, similar to its SRAM, DRAM and Flash product families.

"HyperFlash™ products will be a great addition to ISSI's rapidly expanding Automotive Electronics Council Qualified portfolio of flash products. These new flash solutions complement and broaden our extensive family of SRAM, High Speed DRAM and Mobile DRAM, including LPDDR2 and LPDDR3," said Zastrow.

Availability
Samples of the HyperFlash™ products in both industrial temperature ranges and the automotive temperature ranges from ISSI will be available in the first calendar quarter of 2015.
