GENERAL DESCRIPTION
The LY62W1024 is a 1,048,576-bit low power
CMOS static random access memory organized as
131,072 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 LY62W1024 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY62W1024 operates from a single power
supply of 2.7V ~ 5.5V and all inputs and outputs are
fully TTL compatible

1.WE#, CE# must be high or CE2 must be low during all address transitions.
2.A write occurs during the overlap of a low CE#, high CE2, 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 and CE2 high 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.
