Elpida Memory's WTR (Wide Temperature Range) SDRAM Devices Target Auto GPS and Industrial Markets
128-Megabit and 256-Megabit Memory Devices Offer Flawless Performance in Harsh Environmental Conditions

TOKYO, JAPAN, May 28, 2002 - Elpida Memory, Inc. (Elpida), announced today the availability of high-performance WTR (Wide Temperature Range) Synchronous DRAM (SDRAM) devices for use in automotive GPS, remote communications, and industrial applications. The WTR SDRAMs offer the same functionality and compatibility as standard SDRAM devices, but operate at a much wider range of ambient temperatures (TA= -40 to 85°C) versus standard SDRAM (TA= 0 to 70°C). This makes Elpida WTR SDRAMs ideal for any type of high-performance system that is subject to harsh temperature extremes.
"High-performance computing has expanded from the desktop into many different form factors and operating environments, and there is a strong demand for SDRAM modules that perform flawlessly under a wide range of environmental conditions," said Jun Kitano, director of Technical Marketing for Elpida Memory (USA) Inc. "Elpida is responding to these demands with WTR SDRAMs that are robust enough for almost any application. By utilizing the most advanced circuit design techniques, our WTR SDRAM products offer the same performance and compatibility as standard SDRAMs, but under extreme temperatures."
Elpida's WTR SDRAMs achieve high-speed data transfer using a pipelined 133 Mhz Synchronous DRAM architecture. They are available in 128-Megabit and 256-Megabit densities, and even with their WTR SDRAM functionality, customers are not required to implement a specialized SDRAM controller. This simplifies testing for motherboard and system vendors who design for both standard and rugged environments. The products are packaged in 54-pin TSOP (II).
