Fujitsu MB85RC64A
The MB85RC64A is an 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. The read/write endurance of the nonvolatile memory cells used for the MB85RC64A has improved to be at least 1012 cycles, significantly outperforming Flash memory and E2PROM in the number. The MB85RC64A does not need a polling sequence after writing to the memory such as the case of Flash memory or E2PROM.| Part No. | MB85RC64A |
