Description
The FM22L16 is a 256Kx16 nonvolatile memory that
reads and writes like a standard SRAM. A
ferroelectric random access memory or FRAM 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,
complexities of battery-backed SRAM (BBSRAM).
Fast write timing and unlimited write endurance make
FRAM superior to other types of memory.
In-system operation of the FM22L16 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 /CE or simply by
changing the address. The FRAM memory is
nonvolatile due to its unique ferroelectric memory
process. These features make the FM22L16 ideal for
nonvolatile memory applications requiring frequent
or rapid writes in the form of an SRAM.
The FM22L16 includes a low voltage monitor that
blocks access to the memory array when V

drops
below a critical threshold. The memory is protected
against an inadvertent access and data corruption
under this condition. The device also features
software-controlled write protection. The memory
