Open the CIPO recordAbstract From the Canadian patent
An improved NMOS storage cell for use in shift registers is disclosed. Among other components it, contains a pair of inverters -- one them an enabling inverter. A pre-charge transistor is placed in parallel with the first inverter to decrease the rise time associated with the transition from a logic low level output to a logic high level output. The result of adding the pre-charge transistor to the circuit is to increase the speed of operation of the storage cell without the, accompanying decrease in density with prior art methods where the components must he enlarged. Another aspect of the the present invention which further increases the density of the cell is the elimination of the …
