General Description
The FM28V100 is a 128K x 8 nonvolatile memory
that reads and writes like a standard SRAM. A
ferroelectric random access memory or F-RAM is
nonvolatile, which means that data is retained after
power is removed. It provides data retention for over
10 years while eliminating the reliability concerns,
functional
disadvantages,
and
system
design
complexities of battery-backed SRAM (BBSRAM).
Fast write timing and very high write endurance make
F-RAM superior to other types of memory.
In-system operation of the FM28V100 is very similar
to other RAM devices and can be used as a drop-in
replacement for standard SRAM. Read and write
cycles may be triggered by toggling a chip enable pin
or simply by changing the address. The F-RAM
memory is nonvolatile due to its unique ferroelectric
memory process. These features make the FM28V100
ideal for nonvolatile memory applications requiring
frequent or rapid writes in the form of an SRAM.
