CY7C150  
1Kx4 Static RAM  
Separate I/O paths eliminates the need to multiplex data in  
and data out, providing for simpler board layout and faster sys-  
tem performance. Outputs are three-stated during write, reset,  
deselect, or when output enable (OE) is held HIGH, allowing  
for easy memory expansion.  
Features  
• Memory reset function  
• 1024x4 staticRAM for control storein high-speed com-  
puters  
• CMOS for optimum speed/power  
• High speed  
Reset is initiated by selecting the device (CS = LOW) and tak-  
ing the reset (RS) input LOW. Within two memory cycles all  
bits are internally cleared to zero. Since chip select must be  
LOW for the device to be reset, a global reset signal can be  
employed, with only selected devices being cleared at any giv-  
en time.  
— 10 ns (commercial)  
— 12 ns (military)  
• Low power  
— 495 mW (commercial)  
— 550 mW (military)  
• Separate inputs and outputs

charge  
TTL-compatible inputs and outputs  
Writing to the device is accomplished when the chip select  
(CS) and write enable (WE) inputs are both LOW. Data on the  
four data inputs (D0D3) is written into the memory location  
specified on the address pins (A0 through A9).  
Reading the device is accomplished by taking chip select (CS)  
and output enable (OE) LOW while write enable (WE) remains  
HIGH. Under these conditions, the contents of the memory  
location specified on the address pins will appear on the four  
output pins (O0 through O3).  
The output pins remain in high-impedance state when chip  
enable (CE) or output enable (OE) is HIGH, or write enable  
(WE) or reset (RS) is LOW.  
Functional Description  
The CY7C150 is a high-performance CMOS static RAM de-  
signed for use in cache memory, high-speed graphics, and  
data-acquisition applications. The CY7C150 has a memory re-  
set feature that allows the entire memory to be reset in two  
memory cycles.  
A die coat is used to insure alpha immunity.
