CDP1821C/3
March 1997
High-Reliability CMOS 1024-Word x 1-Bit Static RAM
Description
The CDP1821C/3 is a 1024-word x 1-bit CMOS silicon-on-sapphire (SOS), fully static, random-access memory designed for use in CDP1800 microprocessor systems. This device has a remended 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 necessary to clock the chip-select input or any other input terminal for fully static operation;...
