employing an advanced ferroelectric process. Aferroelectric random access memory or FRAM isnonvolatile but operates in other respects as a RAM.It provides data retention for 45 years whileeliminating the reliability concerns, functionaldisadvantages and system design complexities ofbattery-backed SRAM. Its fast write and high writeendurance make it superior to other types ofnonvolatile memory.In-system operation of the FM1608 is very similar toother RAM based devices. Minimum read- and writecycletimes are equal. The FRAM memory, however,is nonvolatile due to its unique ferroelectric memoryprocess. Unlike BBSRAM, the FM1608 is a trulymonolithic nonvolatile memory. It provides the samefunctional benefits of a fast write without the seriousdisadvantages associated with modules and batteriesor hybrid memory solutions.These capabilities make the FM1608 ideal fornonvolatile memory applications requiring frequentor rapid writes in a bytewide environment. Theavailability of a true surface-mount package improvesthe manufacturability of new designs, while the DIPpackage facilitates simple design retrofits. TheFM1608 offers guaranteed operation over anindustrial temperature range of -40°C to +85°C.
