MB85R1002
The MB85R1002 is an FRAM (Ferroelectric Random Access Memory) chip consisting of 65,536 words x 16 bits of non-volatile memory cells created using ferroelectric process and silicon gate CMOS process technologies. The MB85R1002 is able to retain data without using a back-up battery, as is needed for SRAM. The memory cells used in the MB85R1002 can be used for at least 10 improvement over the number of read and write operations supported by Flash memory and E The MB85R1002 uses a pseudo-SRAM interface that is compatible with conventional asynchronous SRAM.
