General Description
LY625128 General Description
The LY625128 is a 4,194,304-bit low power CMOS static random access memory organized as 524,288 words by 8 bits. It is fabricated using very high performance, high reliability CMOS technology. Its standby current is stable within the range of operating temperature.
The LY625128 is well designed for very low power system applications, and particularly well suited for battery back-up nonvolatile memory application.
The LY625128 operates from a single power supply of 4.5V ~ 5.5V and all inputs and outputs are fully TTL compatible
