Memory ReRAM

8M (1024 K  8) Bit SPI

MB85AS8MT



DESCRIPTION

MB85AS8MT is a ReRAM (Resistive Random Access Memory) chip in a configuration of 1,048,576

words  8 bits, using the resistance-variable memory process and silicon gate CMOS process technologies

for forming the nonvolatile memory cells.

MB85AS8MT adopts the Serial Peripheral Interface (SPI).

MB85AS8MT is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85AS8MT can be used for 1  106 rewrite operations.
