London, July 6 2001 - Fujitsu Microelectronics has introduced stacked multi-chip packages (MCPs) that incorporate high-density NAND Flash memory and Fast Cycle RAM (FCRAM®), developed to provide the speed, density and cost-efficiency required for data storage in the next generation of mobile information terminals.

The functions and services available to users of these mobile information terminals, particularly cellular phones, including e-mail and image transmission, viewing and downloading of home pages and, more recently, playing high-quality video games, continue to expand dramatically.

Fujitsu's new MB84VN23381EJ and MB84VN23391EJ MCP devices provide 64Mbit NAND-type Flash memory and 16Mbit FCRAM with a static RAM interface. The NAND Flash enables page programming in 200 microseconds, random read access in 10 milliseconds, serial read access in 70 nanoseconds max within a page and small block erasure in just 2 milliseconds. The random read access time for the FCRAM SRAM interface is 90 nanoseconds per word. The new MCP accommodates large files, and can rewrite and erase the particularly high volume of serial data required for video applications.

The NAND-type Flash memory uses a x16 configuration, enabling a two-fold speed increase to be achieved compared with the x8-configuration of NAND products now available for cellular phone design. The MB84VN23381EJ includes a common data I/O port for Flash and FCRAM, while the ports on the MB84VN23391EJ are separate.
Samples of the new devices are now available in plastic BGA packages, measuring just 11mm x 12mm x 1.4mm, with a pitch of 0.8mm.
