MB85RS64VY

MB85RS64VY is a 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. This product is specifically targeted for high-temperature environment such as automotive applications.

MB85RS64VY adopts the Serial Peripheral Interface (SPI).

The MB85RS64VY is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85RS64VY can be used for 10¹³ read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and E2PROM.

As MB85RS64VY does not need any waiting time in writing process, the write cycle time of MB85RS64VY is much shorter than that of Flash memories or E2PROM.
