Abstract
A circuit for use in controlling a memory cell coupled to a word line W and to first and second bit lines B1 and B2 includes an enabling flip-flop 20 having set terminal S connected to a source of enabling signals and a reset terminal R connected to an OR gate 22; a word line addressing circuit 25 connected to the output of the enabling flip-flop 20 and to the word line W, and having a terminal ADDR for receiving address information; first and second read/write circuits 29 and 30 connected to corresponding first and second bit lines B1 and B2, respectively, each of the read/write circuits 29 and 30 including a control node WRC and an output node SADO; a logic gate 22 having an output coupled to the reset terminal and having input nodes SADO 0 and SADO 1 connected to the corresponding output nodes of the read/write circuits 29 and 30, and an output flip-flop 33 connected the output nodes SADO 0 and SADO 1 of the read/write circuits 29 and 30.
