General Description
The UMC UM2147 is a 4096-Bit Static Random Access Memory organized 4096 words by 1-bit and is fabricated using UMC's new scaled N-channel silicon gate 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. Separate data input and output pins provide maximum design flexibility. The three-state output facilitates memory expansion by allowing the outputs to be OR-tied to other devices.
The UM2147 offers an au...
