MB85R1002A
■ DESCRIPTIONS
The MB85R1002A is an FRAM (Ferroelectric Random Access Memory) chip consisting of 65,536 words ×
16 bits of nonvolatile memory cells fabricated using ferroelectric process and silicon gate CMOS process
technologies.
The MB85R1002A is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85R1002A can be used for 10 10 read/write operations, which is a significant
improvement over the number of read and write operations supported by Flash memory and E 2 PROM.
The MB85R1002A uses a pseudo-SRAM interface that is compatible with conventional asynchronous SRAM.
