A discharge circuit for rapidly discharging the word lines of random access memories to thereby prevent erroneous reading from or writing into the memory during periods when the word lines are in a mid-state transition between selected and deselected voltage levels. Each discharge circuit associated with the memory word lines includes a transistor that is conductive only when a full select voltage level is applied to the word line and which controls conduction of a second multi-collector transistor coupled between top and bottom lines of a word line pair and a current source to discharge the word line pair during the mid-state transition period and to thus increase the speed capabilities of the memory.
Discharge circuitry for rapidly discharging each of a plurality of electrical conductors when the voltage thereon drops from a first selected voltage level through a mid-state transition toward a second voltage level, said circuitry comprising:
