Functional Description
The CY9C62256 is a high-performance CMOS nonvolatile
RAM employing an advanced magnetic RAM (MRAM)
process. An MRAM is nonvolatile memory that operates as a
fast read and write RAM. It provides data retention for more
than ten years while eliminating the reliability concerns,
functional disadvantages and system design complexities of
battery-backed SRAM, EEPROM, Flash and FeRAM. Its fast
writes and high write cycle endurance makes it superior to
other types of nonvolatile memory.
The CY9C62256 operates very similarly to SRAM devices.
Memory read and write cycles require equal times. The MRAM
memory is nonvolatile due to its unique magnetic process.
Unlike BBSRAM, the CY9C62256 is truly a monolithic nonvol-
atile 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 CY9C62256 ideal for nonvolatile
memory applications requiring frequent or rapid writes in a
bytewide environment.
The CY9C62256 is offered in both commercial and industrial
temperature ranges.
