MB85RC512T集成电路（IC）的存储器规格书PDF中文资料

 DESCRIPTION

The MB85RC512T is an FeRAM (Ferroelectric Random Access Memory) chip in a configuration of 65,536

words  8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the

nonvolatile memory cells.

Unlike SRAM, the MB85RC512T is able to retain data without using a data backup battery.

The read/write endurance of the nonvolatile memory cells used for the MB85RC512T has improved to be

at least 1013 cycles, significantly outperforming other nonvolatile memory products in the number.

The MB85RC512T does not need a polling sequence after writing to the memory such as the case of Flash

memory or E2PROM.
