Description  
The FM22L16 is a 256Kx16 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 high write endurance make the  
F-RAM 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 F-RAM 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 VDD drops  
below VDD min. The memory is protected against an  
inadvertent access and data corruption under this  
condition. The device also features software-  
controlled write protection. The memory array is  
divided into 8 uniform blocks, each of which can be  
individually write protected.
