The Fujitsu MB85RC256V is a 256K Bit FRAM (Ferroelectric Random Access Memory) chip with serial interface (I²C) 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.
