MB85R4002A is a4M Bit 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.
The MB85R4002A uses a pseudo-SRAM interface that is compatible with conventional asynchronous SRAM.
