Ramtron FM21LD16
The FM21LD16 is a 128Kx16 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 FM21LD16 is very similar to other RAM devices and can be used as a drop-in replacement for standard SRAM.| Part No. | FM21LD16 |
