DESCRIPTION

MB85RS64 is a FeRAM (Ferroelectric Random Access Memory) chip in a configuration of 8,192 words 

8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile

memory cells.

MB85RS64 adopts the Serial Peripheral Interface (SPI).

The MB85RS64 is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85RS64 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.

MB85RS64 does not take long time to write data like Flash memories or E2PROM, and MB85RS64 takes

no wait time.
