- DESCRIPTIONS
The MB85R4001A is an FRAM (Ferroelectric Random Access Memory) chip consisting of 524,288 words × 8 bits of nonvolatile memory cells fabricated using ferroelectric process and silicon gate CMOS process technologies.
The MB85R4001A is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85R4001A 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 MB85R4001A uses a pseudo-SRAM interface.
