Description
The CDP1821C/3 is a 1024-word x 1-bit CMOS silicon-on-sap-
phire (SOS), fully static, random-access memory designed for
use in CDP1800 microprocessor systems. This device has a
recommended operating voltage range of 4V to 6.5V.
The output state of the CDP1821C/3 is a function of the
input address and chip-select states only. Valid data will
appear at the output in one access time following the latest
address change to a selected chip. After valid data appears,
the address may be changed immediately. It is not neces-
sary to clock the chip-select input or any other input terminal
for fully static operation; therefore the chip-select input may
be used as an additional address input. When the device is
in an unselected state (CS = 1), the internal write circuitry
and output sense amplifier are disabled. This feature allows
the three-state data outputs from many arrays to be OR-tied
to a common bus for easy memory expansion.
