DATA SHEET DS501-00054-1v0-E Memory FRAM 8 M (512 K Г— 16) Bit
MB85R8M2T
пЃ® DESCRIPTIONS
The MB85R8M2T is an FRAM (Ferroelectric Random Access Memory) chip consisting of 524,288 words
Г— 16 bits of nonvolatile memory cells fabricated using ferroelectric process and silicon gate CMOS process
technologies.
The MB85R8M2T is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85R8M2T 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. The
MB85R8M2T uses a pseudo-SRAM interface. пЃ® FEATURES Bit configuration Read/write endurance Data retention Operating power supply voltage Low power operation : 524,288 words Г— 16 bits
