Monolithic Flash Memory IC 64KB FM1608-120 Bytewide Fram Memory

FM1608-120 - RAMTRON INTERNATIONAL CORPORATION - 64KB BYTEWIDE FRAM MEMORY

Quick Detail:

64Kb Bytewide FRAM Memory

Description:

The FM1608 is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is

nonvolatile but operates in other respects as a RAM. It provides data retention for 10 years while eliminating the reliability concerns, functional disadvantages and system design complexities of battery-backed SRAM. Its fast write and high write endurance make it superior to other types of nonvolatile memory.

In-system operation of the FM1608 is very similar to other RAM based devices. Memory read- and writecycles require equal times. The FRAM memory, however, is nonvolatile due to its unique ferroelectric memory process. Unlike BBSRAM, the FM1608 is a truly monolithic nonvolatile memory. It provides the same functional benefits of a fast write without the serious disadvantages associated with modules and

batteries or hybrid memory solutions.

These capabilities make the FM1608 ideal for nonvolatile memory applications requiring frequent or rapid writes in a bytewide environment. The availability of a true surface-mount package improves the manufacturability of new designs, while the DIP package facilitates simple design retrofits. The FM1608 offers guaranteed operation over an industrial temperature range of -40°C to +85°C.
