MB85R2001
■ DESCRIPTIONS
The MB85R2001 is an FRAM (Ferroelectric Random Access Memory) chip consisting of 262,144 words × 8 bits
of non-volatile memory cells created using ferroelectric process and silicon gate CMOS process technologies.
The MB85R2001 is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85R2001 can be used for 10¹⁰ read/write operations, which is a significant
improvement over the number of read and write operations supported by Flash memory and E²PROM.
The MB85R2001 uses a pseudo-SRAM interface that is compatible with conventional asynchronous SRAM.
