64Kx16 LP SRAM EM6164K600V Series
GENERAL DESCRIPTION
The EM6164K600V is a 1,048,576-bit low power CMOS static random access memory organized as
65,536 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 EM6164K600V is well designed for low power application, and particularly well suited for battery
back-up nonvolatile memory application.
The EM6164K600V operates from a single power supply of 2.7V ~ 3.6V and all inputs and outputs are
fully TTL compatible

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. 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#, 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.
