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 virtually unlimited write endurance make F-RAM superior to other types of memory. In-system operation of the FM28V020 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 FM28V020 ideal for nonvolatile memory applications requiring frequent or rapid writes in the form of an SRAM. The device is available in a 28-pin SOIC, 28-pin TSOP-I, or 32-pin TSOP-I surface mount package. Device specifications are guaranteed over the industrial temperature range -40°C to +85°C.
