FM25V20-PG

2MB串行3V F-RAM存储器 2Mb Serial 3V F-RAM Memory

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.
