The LY6212816 is a 2,097,152-bit low power CMOS
static random access memory organized as 131,072
words by 16 bits. It is fabricated using very high
performance, high reliability CMOS technology. Its
standby current is stable within the range of
operating temperature.
The LY6212816 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY6212816 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible

4.tCLZ, tBLZ, tOLZ, tCHZ, tBHZ 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 , tBHZ is less than tBLZ, tOHZ is less than tOLZ.

Notes :
1.WE#,CE#, LB#, UB# must be high during all address transitions.
2.A write occurs during the overlap of a low CE#, low WE#, LB# or UB# = low.
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#, LB#, UB# 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.
