Low Power Consumption Memory for SiP (x64, Low Power DDR SDRAM) 256M-bit Consumer FCRAM

Introduction

Fujitsu provides a new 256M-bit Consumer FCRAM product optimized for a SiP(System in Package) design, featuring low power consumption for digital consumer electronics.
This FCRAM offers the best solution for memory embedded in various digital consumer electronics in term of system value and cost instead of using DDR SDRAM.

Applications

Digital Consumer Electronics

• Digital TV
• Digital Still Camera
• Digital Video Camera
• Set Top Box
• Portable Media Player (PMP)

Features

The Consumer FCRAM features low power consumption and high performance which are essential to electronic components for digital consumer electronics.

With a 64-bit I/O and CMOS Low Power DDR SDRAM interface, this FCRAM is capable of a maximum 3.46GByte/s of high-speed data transfer performance while keeping low power consumption.

An SiP solution using the FCRAM provides the advantages of simplified board design and reduced costs.

Low Power Consumption

• Enables greater reduction of power consumption than using two(2) DDR2 SDRAMs because no termination resistors (on board or ODT:On Die Termination) are necessary. (The termination resistors are needed for high speed memory like DDR2 SDRAM to avoid distortion of signals caused by reflections.)
• Using one(1) FCRAM reduces power consumption by a maximum of approx. 1W (by 70%), compared with the equivalent operation using two(2) DDR2 SDRAMs.

High-Speed Data Transfer Rate

• Capable of max. 3.46GByte/s of data transfer performance with 64-bit I/O and max. operating frequency of 216MHz, double the speed of typical DDR2 SDRAMs (x16, 400MHz).

SiP-optimized memory design

• SiP-optimized design: pad assignment suited for chip stacking and low power consumption with CMOS interfaces.
