FM25V20-DGTR集成电路（IC）的存储器规格书PDF中文资料

描述 Description

The FM25V20 is a 2-megabit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 10 years while eliminating the complexities, overhead, and system level reliability problems caused by Serial Flash and other nonvolatile memories.
