FeRAM

Overview

Memory FeRAM 256 K (32 K x 8) Bit I2C MB85RC256VPNF-G-JNERE1

■ DESCRIPTION

The MB85RC256VPNF-G-JNERE1 is an FeRAM (Ferroelectric Random Access Memory) chip in a configuration of 32,768 words x 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the non-volatile memory cells.

Different from SRAM, the MB85RC256VPNF-G-JNERE1 can keep and maintain data without needing a data backup battery.

The read/write endurance of the nonvolatile memory cells used for the MB85RC256V has improved to be at least 1 trillion cycles, obviously outperforming other nonvolatile memory products in the number.

The MB85RC256VPNF-G-JNERE1 does not need a polling sequence after writing to the memory such as the case of Flash memory or EEPROM.
