MB85R4002A Datasheet Memory Fram

Manufacturer: Fujitsu Semiconductor Limited

Overview: FUJITSU SEMICONDUCTOR DATA SHEET Memory FRAM 4 M Bit (256 K × 16) MB85R4002A DS501-00006-3v1-E.

General Description

S The MB85R4002A is an FRAM (Ferroelectric Random Access Memory) chip consisting of 262,144 words × 16 bits of nonvolatile memory cells fabricated using ferroelectric process and silicon gate CMOS process technologies.

The MB85R4002A is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85R4002A can be used for 1010 read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and E2PROM.

Key Features

  • Bit configuration : 262,144 words × 16 bits.
