Fujitsu, NEC and Toshiba Agree on Common Specifications for Next-Generation Pseudo SRAM User Interface for Mobile Applications|
14 March, 2002
Tokyo, March 14, 2002 -- Fujitsu Limited, NEC Corporation and Toshiba Corporation announced today that they have reached an agreement on common specifications for the next generation of Pseudo Static Random Access Memory (PSRAM) *1 devices. The new common specifications for next-generation mobile Pseudo SRAM user interface emerged from discussions among the three companies that began in October of last year.
Each of the three companies will independently manufacture and market PSRAM products based on the common specifications, with product introduction expected to begin in the second half of fiscal 2002.
Because the new specifications standardize the packaging and pin layout for the PSRAM, customers will benefit from a uniform design format, eliminating the need to customize designs for each product. This advantage will help shorten the design cycle and dramatically improve design efficiency. Also, since the three companies are using common specifications, they can also act as alternative sources for each other, helping to ensure a stable market supply.
Recent performance enhancements of cellphones and other mobile equipment, such as PDAs, have created demand for more onboard memory. In the past, this "working memory" came in the form of low-power SRAM, but because of the difficulty of scaling up low-power SRAM to handle large densities, suppliers were unable to respond rapidly to the market need for higher densities. Instead, high-density PSRAM, which can readily scale up to 16 Mbit or more, is now being widely used. Also, high-speed needs are rapidly expanding in cellphone and PDA applications, and PSRAM is responding to it as well.
PSRAM had been designed with an emphasis on compatibility with SRAM, but each manufacturer has developed its own product specifications, with different pinouts, limiting compatibility. This has also caused problems for stacked multi-chip packages (MCPs) that contained PSRAM chips.
The common specifications resolve the compatibility problem by defining memory densities, supply voltage ranges, control-pin names, some functions, packaging and other user-interface specifications.
Specifically, the new specifications cover:
In September 1998, the three companies promulgated common specifications for stacked MCPs that include both flash memory and SRAM. These specifications will be expanded to incorporate the new common spec for next-generation PSRAM, forming the basis for common specifications for next-generation PSRAM, forming the basis for common specifications for next-generation MCPs that include PSRAM. This development will bring the benefits of design format efficiencies and a stable market supply to MCP customers as well.
