MB85RS2MT
■ DESCRIPTION
MB85RS2MT is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of 262,144
words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the
nonvolatile memory cells.
MB85RS2MT adopts the Serial Peripheral Interface (SPI).
The MB85RS2MT is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS2MT can be used for 10¹³ read/write operations, which is a significant
improvement over the number of read and write operations supported by Flash memory and E²PROM.
MB85RS2MT does not take long time to write data like Flash memories or E²PROM, and MB85RS2MT takes
no wait time.
