5. Apparatus for pulling down the word line voltage when a word is to be deaddressed in a memory of the kind having a plurality of words and a top word line and a bottom word line associated with each word, said apparatus comprising, detecting means for detecting a signal that the address of a word is to be changed, amplifying means operatively associated with the detecting means for amplifying the detected signal, steering means operatively associated with the amplifying means for steering a pull-down current to the bottom word line to commence pulling the word down in response to the amplified signal and for maintaining that pull-down current on the bottom word line until the word is deaddressed, said amplifying means including current switch means operatively associated with a word line for detecting the fact that the word has been pulled down and effective to cause the level shifter and steering means to steer the pull-down current away from the bottom pull-down line after the word has been deaddressed.
