P4C1024
HIGH SPEED 128K x 8
DUAL CHIP ENABLE
CMOS STATIC RAM
The P4C1024 device provides asynchronous opera-
tions with matching access and cycle times. Memory
locations are specified on address pins A
0 to A16.
Reading is accomplished by device selection (
CE
1 low
and CE
2 high) and output enabling (OE) while write
enable (
WE) remains HIGH. By presenting the ad-
dress under these conditions, the data in the ad-
dressed memory location is presented on the data
input/output pins. The input/output pins stay in the
HIGH Z state when either
CE
1 or OE is HIGH or WE
or CE
2 is LOW.
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.
