WORD LINE SELECTION CIRCUIT FOR SCHOTTKY-COUPLED MEMORY CELL ARRAY.

A selection circuit is presented which offers a fast selection technique for a Schottky-coupled memory cell array, where the drain line and word line are pulled down for selection. The advantages of the circuit include the following: (1) a transient active pull down of the drain line to provide a fast selection mode, (2) an active pull up of the word line to provide a fast deselection mode, and (3) a well controlled fully selected drain line current which is important for the operation of the cells during a read or write mode.
