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.
