Fujitsu Unveils World's First Multi-Chip Package with Burst Mode Functionality

-Features 128Mb Flash Memory and 64Mb Mobile FCRAM-

Fujitsu Limited

Tokyo, June 02, 2003

Fujitsu Limited today announced the development of a new memory product for next-generation mobile phones and other high-performance mobile applications, the MB84SR6H5K5K1, a multi-chip package (MCP) combining Mobile Fast Cycle RAM (FCRAM)(1) and burst mode(2) flash memory. Fujitsu is shipping samples of the new chip package starting today.

The new multi-chip package includes one 128Mbit (Mb) NOR-type flash memory and two 64Mb Mobile FCRAM chips compliant with the Common Specification for Mobile RAM (COSMORAM)(3). Both memory units are capable of burst-mode operation at 66MHz, enabling high-speed data access. Moreover, the new MCP is a low-voltage device, requiring only 1.8V of power.

The product is designed especially for use in 3G mobile phones, where the burst mode operation will deliver the high-speed data transfer rates essential for sending and playback of streaming video and other multimedia functions.

Fujitsu plans to extend this line to suit diverse customer needs, adding a model with 64Mb flash memory and 32Mb Mobile FCRAM, and increasing burst frequencies to 80MHz and even 100MHz.

Features

1. Fast access times

  • Adding burst-mode capabilities to both the flash memory and Mobile FCRAM allows for faster read operations.
  • Burst-mode access times are 11ns for flash memory, 12ns for Mobile FCRAM (at 66MHz).
  • Asynchronous read/write operations also supported.

2. Low power consumption

  • Operating on 1.8V power, the flash memory requires a maximum of 10µA, the Mobile FCRAM a maximum of 120µA of standby current.
  • The Mobile FCRAM also includes a power-down mode that dramatically reduces its power requirements (max 10µA).

3. Pin layout shared by all three COSMORAM-developing companies

  • Support for the COSMORAM standard (including pin layouts) simplifies board and connector design for customers.

Trademark notice

  • FCRAM is a registered trademark of Fujitsu Limited
  • All other product names and company names mentioned herein are the trademarks or registered trademarks of their respective firms.

  • [1] Mobile Fast Cycle RAM (FCRAM)

    FCRAM is an advanced memory core design, proprietary to Fujitsu, with low power consumption and fast operation. Mobile FCRAM is a pseudo-SRAM technology that couples an FCRAM core to an SRAM interface.

  • [2] burst mode

    A special mode of operation for memory enabling fast, continuous reads synchronized to the system clock, so that a large amount of information can be read in a large block, simply by specifying one partial address. FCRAM adds the ability to perform write operations in burst mode as well.

  • [3] Common Specification for Mobile RAM (COSMORAM)

    A specification developed jointly by Fujitsu Limited, NEC Electronics Corp. and Toshiba Corp., and announced on February 17, 2003. Refers to a standard for burst mode pseudo-SRAM chips and MCPs containing these chips.
