Memory FRAM
16 K (2 K × 8) Bit SPI
MB85RS16
■ DESCRIPTION
MB85RS16 is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of 2,048 words ×
8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile
memory cells.
MB85RS16 adopts the Serial Peripheral Interface (SPI).
The MB85RS16 is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS16 can be used for 10
12
read/write operations, which is a significant
improvement over the number of read and write operations supported by Flash memory and E
2
PROM.
MB85RS16 does not take long time to write data like Flash memories or E
2
PROM, and MB85RS16 takes
no wait time.
