DESCRIPTION
MB85RS128B is a FeRAM (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.
MB85RS128B adopts the Serial Peripheral Interface (SPI).
The MB85RS128B is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS128B 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.
MB85RS128B does not take long time to write data like Flash memories or E2PROM, and MB85RS128B
takes no wait time.
