Fujitsu MB85R1002
The MB85R1002 is an FRAM (Ferroelectric Random Access Memory) chip in a configuration of 65,536 words x 16 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells. The memory cells used for the MB85R1002 has improved at least 1010 times of read/write access, significantly outperforming FLASH memory and E2PROM in endurance. The MB85R1002 uses a pseudo - SRAM interface compatible with conventional asynchronous SRAM.FEATURES
