Functional Description
The CY7C1034DV33 is a high-performance CMOS static
RAM organized as 256K 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
1
LOW, CE
2
HIGH
and CE
3
LOW) while forcing the Write Enable (WE) input
LOW.
To read from the device, enable the chip by taking CE

CE
2
HIGH and CE
3
LOW while forcing the Output Enable (OE)
LOW and the Write Enable (WE) HIGH. See the truth table at
the back of this data sheet for a complete description of Read
and Write modes.
The 24 I/O pins (I/O
0
鈥揑/O

) are placed in a high-impedance
state when the device is deselected (CE

during a Write operation. (CE
