DESCRIPTION

The P4C1024 is a 1,048,576-bit high-speed CMOS

static RAM organized as 128Kx8. The CMOS memory

requires no clocks or refreshing, and has equal access

and cycle times. Inputs are fully TTL-compatible. The

RAM operates from a single 5V±10% tolerance power

supply.

Access times of 15 nanoseconds permit greatly en-

hanced system operating speeds. CMOS is utilized to

reduce power consumption to a low level. The P4C1024

is a member of a family of PACE RAM™ products offer-

ing fast access times.

The P4C1024 device provides asynchronous operations

with matching access and cycle times. Memory loca-

tions are specified on address pins A

to A

. Reading

is accomplished by device selection (CE

low and CE

high) and output enabling (OE) while write enable (WE)

remains HIGH. By presenting the address under these

conditions, the data in the addressed memory location

is presented on the data input/output pins. The input/

output pins stay in the HIGH Z state when either

is HIGH or

or CE

is LOW.
