Memory FRAM
128 K (16 K × 8) Bit I
MB85RC128
■ DESCRIPTION
■ FEATURES
The MB85RC128 is a FRAM (Ferroelectric Random Access Memory) Stand-Alone chip in a configuration
of 16,384 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for
forming the nonvolatile memory cells.
The MB85RC128 adopts the two-wire serial interface.
Unlike SRAM, the MB85RC128 is able to retain data without using a data backup battery.
The read/write endurance of the nonvolatile memory cells used for the MB85RC128 has improved to be at
least 10
The MB85RC128 does not need a polling sequence after writing to the memory such as the case of Flash
memory nor E
