MB85R256H Memory FRAM CMOS 256 K (32 K X 8) Bit

The MB85R256H is an FRAM (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 nonvolatile memory cells. Unlike SRAM, MB85R256H is able to retain data without back-up battery. The memory cells used for the MB85R256H has improved at lea.
