UM2148

(DUMO ========= UM2148 1K x 4 High Speed NMOS SRAM Features 45 ns maximum access time No cloS;ks or strobes required Automatic CE power down Identical cycle and access times Single+5V supply (± 10%) Pinout and function compatible to SY2148 Industry standard 2114 pinout Totally TTL compatible all inputs and outputs Common data input and output High density 18-pin package Three-state output General Description The UMC UM2148 is a 4096-Bit Static Random Access Memory organized 1024 words by 4 bits 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. Common data input and output pins provide maximum design flexibility. The three-state output facilitates memory expansion by allowing the outputs to be ...
