Fujitsu introduces 16Mbit Mobile Phone memory

San Jose, Calif. -- Fujitsu Limited and Fujitsu Microelectronics, Inc. (FMI) today introduced the industry's newest Application Specific Memory (ASM), a second-generation 16 Mbit RAM with enhanced power requirements as low as 70 microamps.

Fujitsu's new MB82D01171A is designed for next-generation mobile phone applications such as Internet access, music distribution, e-mail, video post cards, information and location-based services. The new ASMs meet the expanded memory requirements that support the advanced infrastructure and high-speed data rates required by new mobile cellular technology.

The MB82D01171A is based on Fujitsu's Fast Cycle RAM (FCRAM) architecture originally announced in June 1998 at the VLSI Symposium. Previous members of the ASM series, the MB82D01160 and MB82D01161, were introduced last June and are now in production.

The new ASMs inherit an asynchronous SRAM-type interface and refresh-free operation with improved low power for long battery life. This makes it easy to upgrade memory without the need for significant changes in a system architecture.

"Fujitsu expects that the FCRAM technology will make a significant design contribution to a wide range of applications," said Fumio Baba, vice president of FMI's system devices group. "The FCRAM products introduced today open the door to new RAM usage in next-generation mobile phones and other applications including EDGE (Enhanced Data Rates for GMS Evolution), WCDMA (Wideband Code Division Multiple Access), CDMA2000 and others. In fact, the current version has been launched into the mobile phone market successfully and new versions will expand our base of applications and customers."

Application Specific Memory Products Meet Multi-market Requirements In recent years, the number of end products that use DRAMs has increased rapidly in market sectors such as computer products (PCs, workstations and servers), consumer products (digital TVs, digital still cameras, video disks and set-top boxes) and telecommunications and networking-related products (switches and routers, mobile/cellular phones, PDAs and network servers). The different applications require higher performance and more diversified memory products, thus segmenting the DRAM market based on applications and performance. Since conventional commodity DRAMs cannot satisfy the different requirements of those various applications, ASM products are becoming essential, particularly for the rapidly evolving multimedia, networking and graphics systems. The trend is similar to the market shift that impacted logic devices.

The variety of products in Fujitsu's new series reflects the diversity of applications that can be served using the revolutionary FCRAM core technology. FCRAM includes memory-array segmentation and internal pipelining that speed random access and reduce power consumption.

Fujitsu continues to develop and supply high value-added Application Specific Memory products based on customer needs in different market segments. These products will incorporate Fujitsu's high-speed, low-power FCRAm core technology, high-speed interface technology and industry-leading small packaging technologies. The company plans to continuously enhance the speed, low power and capacity of these initial FCRAM products, with additional versions due by the second half of calendar year 2001.
