ReRAM

Overview

8M (1024 K x 8) Bit SPI MB85AS8MT DESCRIPTION

MB85AS8MTPW-G-KBAERE1 is a ReRAM (Resistive Random Access Memory) chip in a configuration of 1,048,576 words x 8 bits, using the resistance-variable memory process and silicon gate CMOS process technologies for forming the nonvolatile memory cells.

MB85AS8MTPW-G-KBAERE1 adopts the Serial Peripheral Interface (SPI).

MB85AS8MTPW-G-KBAERE1 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 x 106 rewrite operations.
