512K X 8 BIT LOW POWER CMOS SRAM
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

Notes : 1.WE#, CE# must be high during all address transitions. 2.A write occurs during the overlap of a low CE#, low WE#. 3.During a WE# controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the drivers to turn off and data to be placed on the bus. 4.During this period, I/O pins are in the output state, and input signals must not be applied. 5.If the CE# low transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state. 6.tOW and tWHZ are specified with CL = 5pF. Transition is measured 500mV from steady state.
