Fujitsu, NEC and Toshiba Agree on Common Specifications for “Burst Mode" Pseudo SRAM User Interface

San Jose, CA and Tokyo, February 17, 2003 — Fujitsu Microelectronics America, Inc. (FMA), Fujitsu Limited, NEC Electronics Corporation and Toshiba Corporation announced today that they have reached an agreement on common specifications for Pseudo Static Random Access Memory (PSRAM) devices that feature burst mode function enabling fast access operation. Each of the three companies will independently manufacture and market PSRAM products based on the common specifications, which are to be called Common Specifications for Mobile RAM (COSMORAM), with product introduction expected to begin in the first half of fiscal 2003.

Pseudo SRAM (PSRAM) is a memory device that uses a DRAM cell for high density and low bit cost, and that has an asynchronous SRAM external interface to facilitate efficient system design. It is well suited for cellular phone applications, where the need for higher density working RAM is rapidly growing as more features and functions are implemented.

In September 1998, the three firms promulgated common specifications for stacked multi-chip packages (MCPs) that include both flash memory and SRAM. Then in March 2002, it was announced that the three companies agreed on common specifications for PSRAMs that feature page mode function, forming the basis for a common spec for the page mode PSRAM and stacked MCPs that include the PSRAM. Defining user-interface specifications for high-speed, high-density PSRAMs resolved compatibility problems, thereby allowing customers to efficiently implement the PSRAM devices of all three firms.

The trio of companies has now expanded the agreement to include common specifications for a burst mode PSRAM user interface and the stacked MCPs that house the PSRAMs. Burst mode function enables high-performance operation superior to fast page mode, making it ideally suited to respond to the high-speed processing needs of next-generation cell phones and other mobile equipment, such as PDAs.

Because the specifications for burst mode PSRAM, much like those adopted for page mode PSRAM, standardize the basic electrical properties, packaging and pin layout, 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. In addition, since the three companies are using common specs, they can also act as alternative sources for each other, helping to ensure a stable market supply.

"The common specifications and standardization enabled by the Pseudo SRAM will reduce cost, design time, and inefficiencies for mobile applications," said Keith Horn, vice president, marketing, Fujitsu Microelectronics America. "These benefits are particularly important as new generations of wireless devices such as cell phones and PDAs add impressive new functions and capabilities such as video and advanced Internet access. As an example, the typical access time for the Burst Mode FCRAM is 12 nanoseconds, compared with the page mode access time of 25 nanoseconds. So the high speed FCRAM offers significant benefits for rapid Internet connections over cellular phones."

The COSMORAM specifications for burst mode PSRAM user interface cover:

• Densities
• Supply voltage range
• Control pin names
• Truth table
• Partial refresh function (refresh size and corresponding base address assignment)
• Burst mode function (burst length* and corresponding addressing)
• Mode register defaults
• Mode-register setting method
• Power-on sequence
• Pinouts
• Packaging

Glossary
Truth table: A table defining how a device's operation mode correlates to the external signals used to set that mode.

Partial refresh: This is a feature and operating mode for devices in standby mode that limits current consumption. It refreshes some, but not all, of the bits. If the refreshed bits are storing data, the current flow will be greater, but if they are not, the current flow can be kept to a minimum.

Burst length: Burst mode is a technique to improve a device's memory-access performance. In burst mode, by synchronizing clock input from external, data of a certain number can be read out rapidly and continuously with short cycle. The "burst length" is that number of data to be output continuously.

Mode register: An internal register that stores the control code used to govern the device's operating mode, set externally.

Power-on sequence: A sequence of signal voltages passed through a control pin after the supply voltage is applied to it, which initializes the internal state of the device.
