UM2149 Description
The UMC UM2149 is a 4096-8it Static Random Access Memory organized 1024 words by 4 bits and is fabricated using UMC's new N-channel Silicon-Gate HMOS technology. It is designed using fully static circuitry, therefore requiring no clock or refreshing to operate. Address set-up times are not required and the data is read out non-destructively with the same polarity as the input data.
