Memory FeRAM

256 K (32 K  8) Bit I2C

MB85RC256V



DESCRIPTION

The MB85RC256V is an 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

nonvolatile memory cells.

Unlike SRAM, the MB85RC256V is able to retain data without using a data backup battery.

The read/write endurance of the nonvolatile memory cells used for the MB85RC256V has improved to be

at least 1012 cycles, significantly outperforming other nonvolatile memory products in the number.

The MB85RC256V does not need a polling sequence after writing to the memory such as the case of Flash

memory or E2PROM.
