MB85RS128A
■ DESCRIPTION
MB85RS128A is a 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 1010 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 unlike Flash memories nor E2PROM, and MB85RS128A
takes no wait time.
