 DESCRIPTION
The MB85RC256VN 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 MB85RC256VN is able to retain data without using a data backup battery.
The read/write endurance of the nonvolatile memory cells used for the MB85RC256VN has improved to be
at least 1012 cycles, significantly outperforming other nonvolatile memory products in the number.
The MB85RC256VN does not need a polling sequence after writing to the memory such as the case of Flash
memory or E2PROM.
