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.
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.
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.
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 (D
0
D
3
) is written into the memory location
specified on the address pins (A
0
through A
9
).
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 (O
0
through O
3
).
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.
A die coat is used to insure alpha immunity.
