MB85RS128A is a 128K Bit FRAM (Ferroelectric Random Access Memory) chip in a configuration of 16,384 words ×8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells.
MB85RS128A adopts the Serial Peripheral Interface (SPI).
The MB85RS128A is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS128A can be used for 1012
read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and E²PROM. MB85RS128A does not take long time to write data like Flash memories or E²PROM, and MB85RS128A takes no wait time.
