128-Word X 8-Bit Static Random-Access Memory
Features: Fast access time:
450 ns at Voo= 5 V; 250 ns at Voo = 10 V Common data inputs and outputs Multiple-chip select inputs to simplify memory system expansion
The RCA-CDP1823 and CDP1823C are 128-word by 8-bit
CMOS SOS static random-access memories. These memories are compatible with general-purpose microprocessors. The two memories are functionally identical. They differ in that the CDP1823 has a recommended operating
voltage range of 4 to 10.5 volts, and the CDP1823C has a recommended operating
voltage range of 4 to 6.5 volts.
The CDP1823 memory has 8 common data input and data output terminals for direct connection to...
