The LY62256 is a 262,144-bit low power CMOS static
random access memory organized as 32,768 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 LY62256 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62256 operates from a single power supply
of 2.7~5.5V and all inputs and outputs are fully TTL
compatible

Notes:
1. VIH(max) = VCC + 3.0V for pulse width less than 10ns.
2. VIL(min) = VSS - 3.0V for pulse width less than 10ns.
3. Over/Undershoot specifications are characterized, not 100% tested.
4. Typical values are included for reference only and are not guaranteed or tested.
Typical valued are measured at VCC = VCC(TYP.) and TA = 25℃

Notes :
1.WE# is high for read cycle.
2.Device is continuously selected OE# = low, CE# = low.
3.Address must be valid prior to or coincident with CE# = low,; otherwise tAA is the limiting parameter.
4.tCLZ, tOLZ, tCHZ and tOHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
5.At any given temperature and voltage condition, tCHZ is less than tCLZ , tOHZ is less than tOLZ.

Notes :
1.A write occurs during the overlap of a low CE#, low WE#.
2.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.
3.During this period, I/O pins are in the output state, and input signals must not be applied.
4.If the CE# low transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state.
5.tOW and tWHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
