■ DESCRIPTION
The MB85RC256V is an FRAM (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.
