Memory FRAM

64 K (8 K

MB85RC64A

■ DESCRIPTION

The MB85RC64A is an FRAM (Ferroelectric Random Access Memory) chip in a configuration of 8,192

words

× 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the

nonvolatile memory cells.

Unlike SRAM, the MB85RC64A is able to retain data without using a data backup battery.

The read/write endurance of the nonvolatile memory cells used for the MB85RC64A has improved to be at

The MB85RC64A does not need a polling sequence after writing to the memory such as the case of Flash
