CY7C1007B

1M x 1 Static RAM

Writing to the devices is accomplished by taking Chip Enable

(CE) and Write Enable (WE) inputs LOW. Data on the input pin

(D_IN) is written into the memory location specified on the ad-

dress pins (A₀through A₁₉).

Features

• High speed

— t_AA= 12 ns

Reading from the devices is accomplished by taking Chip En-

able (CE) LOW while Write Enable (WE) remains HIGH. Under

these conditions, the contents of the memory location speci-

• CMOS for optimum speed/power

• Automatic power-down when deselected

• TTL-compatible inputs and outputs

fied by the address pins will appear on the data output (D_OUT

)

pin.

Functional Description

The output pin (D_OUT) is placed in a high-impedance state

when the device is deselected (CE HIGH) or during a write

operation (CE and WE LOW).

The CY7C107B and CY7C1007B are high-performance

CMOS static RAMs organized as 1,048,576 words by 1 bit.

Easy memory expansion is provided by an active LOW Chip

Enable (CE) and three-state drivers. These devices have an

automatic power-down feature that reduces power consump-

tion by more than 65% when deselected.

The CY7C107B is available in a standard 400-mil-wide SOJ;

the CY7C1007B is available in a standard 300-mil-wide SOJ.
