CYPRESS, IDT AND MICRON TEAM TO PROVIDE
NEW QDR™ SRAM ARCHITECTURE

New SRAM Architecture Targets High-Bandwidth Applications
Operating at Data Rates Above 200 MHz

SAN JOSE, Calif., July 26, 1999 Cypress Semiconductor Corp. (NYSE: CY), IDT, Inc. (Nasdaq:
IDTI) and Micron Technology Inc. (NYSE: MU) today announced that they have jointly defined and
developed a new SRAM architecture for future high-performance communications applications.
The new Quad Data Rate (QDR™) SRAMs target the next generation of switches and routers that
operate at data rates above 200 MHz.

The three companies are working closely together to ensure that customers will have multiple
sources for the new SRAMs by developing pin- and function-compatible products. Each partner is
providing system expertise and product direction, giving customers the benefit of a wide range of
market experience and innovative technology.

The development of the unique QDR SRAM architecture included extensive input from networking
industry leaders. The devices are designed to greatly increase memory bandwidth compared to
existing SRAM solutions in applications such as switches and routers, and will serve as the main
memory for look-up tables, linked lists and controller buffer memory. A family of high-performance
QDR SRAMs is defined to ensure customers have the security of consistent multiple supplier
roadmaps.

"The popular Zero Bus Turnaround (ZBT®) and No Bus Latency (NoBl™) architectures are well
suited for today's systems operating with data rates up to 200 MHz," said Jess Huffman, SRAM
industry analyst for Cahners In-Stat Group. "As explosive Internet growth continues, we will see
increased demand for higher speed systems. Designers of these new systems will be eager for the
performance boost offered by QDR SRAMs, and multiple sourcing by three established vendors will
expedite its acceptance."

ZBT and NoBL products, with 3.3-volt or 2.5-volt standard LVTTL I/Os and a flexible data
structure, meet the requirements of today's communications systems operating between 66 MHz
and 200 MHz. Targeting emerging systems operating beyond 200 MHz data rates, the new QDR
SRAMs will have two ports that independently run at double data rate (DDR), resulting in four data
items per clock cycle. Depending upon the application, the new QDR SRAMs can more than double
the SRAM bandwidth.

Each vendor will design and manufacture the devices in its own technology and fabrication
facilities, and will deliver products according to its own internal development schedules. All expect
to make specific product availability announcements during the next year. More information on the
QDR SRAM technology can be obtained at www.QDRSRAM.com.
