FeRAM

Overview

Memory FeRAM 256 K (32 K x 8) Bit I2C MB85RS256BPNF-G-JNERE1

■ DESCRIPTION

MB85RS256BPNF-G-JNERE1 is a FeRAM (Ferroelectric Random Access Memory) chip in a configuration of 32,768 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the non-volatile memory cells.

MB85RS256BPNF-G-JNERE1 uses the Serial Peripheral Interface (SPI).

The MB85RS256BPNF-G-JNERE1 can keep data without needing a back-up battery, which is needed for SRAM.

The memory cells used in the MB85RS256B can be used for 1 trillion read/write operations, which is a great improvement over the number of read and write operations provided by Flash memory and EEPROM.

MB85RS256BPNF-G-JNERE1 does not take long time to write data like Flash memories or EEPROM, and MB85RS256B doesn’t need time to wait.
