DATA SHEET DS501-00060-1v0-E 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. ■ FEATURES
