High Speed Super Low Power SRAM

8K-Word By 8 Bit

WS6264

GENERAL DESCRIPTION

The

WS6264

is a high performance, high speed and super low power CMOS Static Random

Access Memory organized as 8,192 words by 8bits and operates from a single 4.5V to 5.5V supply voltage.

Advanced CMOS technology and circuit techniques provide both high speed, super low power features and

maximum access time of 70ns in 5.0V operation. Easy memory expansion is provided by using two chip

enable inputs (/CE1, CE2) and active LOW output enable (/OE).

The

WS6264

has an automatic power down feature, reducing the power consumption significantly

when chip is deselected. The

WS6264

is available in JEDEC standard 28-pin SOP(300 mil) and PDIP

(600 mil) packages.

FEATURES

Operation voltage : 4.5 ~ 5.5V

Ultra low power consumption:

Operating current 1mA@1MHz & CMOS standby current 1.0uA (Typ.) in Vcc=5.0V

High speed access time: 70ns.

Automatic power down when chip is deselected.

Three state outputs and TTL compatible.

Data retention supply voltage as low as 2.0V.

Easy expansion with /CE1, CE2 and /OE options.
