MB85RS64A
■ DESCRIPTION
MB85RS64A is a FRAM (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.
MB85RS64A adopts the Serial Peripheral Interface (SPI).
The MB85RS64A is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS64A 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.
MB85RS64A does not take long time to write data unlike Flash memories nor E²PROM, and MB85RS64A
takes no wait time.
