Abstract
A memory cell for an associative storage memory device includes a transmission gate which is rendered conductive or non-conductive in response to a potential on a word line for transferring information between an information hold circuit and a bit line or between the information hold circuit and an inverted bit line. Match line are precharged to ground and supply potentials, respectively, and, thereafter, a retrieval circuit compares information on the bit line or inverted bit line with information held in the information hold circuit and produces a control signal to control the potentials on the match lines in accordance with the result of comparison. After the match lines are precharged, a gating circuit is rendered conductive in response to potentials on output control line and inverted output control line to thereby couple the control signal to the match lines.
