INTRODUCTION

TM
UT8Q1024K8 Quantified Commercial Off-the-
Shelf product is a high-performance 1M byte (8Mbit) CMOS
static RAM built with two individual 524,288 x 8 bit SRAMs
with a common output enable. Memory access and control is
provided by an active LOW chip enable (En), an active LOW
output enable (G). This device has a power-down feature that
reduces power consumption by more than 90% when deselected
.
Writing to each memory is accomplished by taking one of the
chip enable (En) inputs LOW and write enable (Wn) inputs
LOW. Data on the I/O pins is then written into the location
specified on the address pins (A
0
through A
18
). Reading from
the device is accomplished by taking one of the chip enable (En)
and output enable (G) LOW while forcing write enable (Wn)
HIGH. Under these conditions, the contents of the memory
location specified by the address pins will appear on the I/O pins.
Only one SRAM can be read or written at a time.
The input/output pins are placed in a high impedance state when
the device is deselected (En HIGH), the outputs are disabled (G
HIGH), or during a write operation (En LOW and Wn LOW).
