世纪芯CY9C62256-70PC芯片解密

Cypress半导体公司生产高性能IC产品，其优异性能常用于数据传输、远程通讯、PC和军用系统。
　　下面以CY9C62256-70PC芯片简要介绍其功能供大家参考：
　　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.
