3-Mbit (128K X 24) Static RAM

Functional Description

The CY7C1024DV33 is a high performance CMOS static RAM
organized as 128K words by 24 bits. This device has an
automatic power down feature that significantly reduces power
consumption when deselected.
To write to the device, enable the chip (CE
and CE
LOW), while forcing the Write Enable (WE) input LOW.
3
To read from the device, enable the chip by taking CE
HIGH, and CE
LOW while forcing the Output Enable (OE) LOW

and the Write Enable (WE) HIGH. See the
7 for a complete description of Read and Write modes.
