CY7C182  
8Kx9 Static RAM  
The CY7C182, which is oriented toward cache memory appli-  
cations, features fully static operation requiring no external  
clocks or timing strobes. The automatic power-down feature  
reduces the power consumption by more than 70% when the  
circuit is deselected. Easy memory expansion is provided by

• CMOS for optimum speed/power

An active-LOW Write Enable signal (WE) controls the writ-  
ing/reading operation of the memory. When CE and WE in-  
puts are both LOW, data on the nine data input/output pins

• TTL-compatible inputs and outputs

• Easy memory expansion with CE , CE , OE options

Functional Description  
Under these conditions, the contents of the location addressed  
by the information on address pins is present on the nine data  
input/output pins.  
The CY7C182 is a high-speed CMOS static RAM organized  
as 8,192 by 9 bits and it is manufactured using Cypress’s high-  
performance CMOS technology. Access times as fast as 25 ns  
are available with maximum power consumption of only 770  
mW.  
The input/output pins remain in a high-impedance state unless  
the chip is selected, outputs are enabled, and write enable  
(WE) is HIGH.  
A die coat is used to insure alpha immunity.
