Ramtron FM20L08
The FM20L08 is a 128K x 8 nonvolatile memory that reads and writes like a standard SRAM. It provides data retention for over 10 years while eliminating the reliability concerns, functional disadvantages, and system design complexities of battery-backed SRAM (BBSRAM). In-system operation of the FM20L08 is very similar to other RAM devices and can be used as a drop-in replacement for standard SRAM.| Part No. | FM20L08 |

DESCRIPTION
A ferroelectric random access memory or FRAM is nonvolatile, which means that data is retained after power is removed. Fast write timing and unlimited write endurance make FRAM superior to other types of memory.
