Abstract
A driver circuit for use in a semiconductor memory array is disclosed. The memory array includes a plurality of the driver circuits, each used to drive a word line in the memory array. The driver circuit of the present invention includes a pull up portion and an active pull down portion. The pull up portion includes a pair of cascaded transistors arranged to pull up an output node coupled to the word line. The active pull down portion includes a pair of cascaded transistors arranged to pull down the output node coupled to the word line. A control feedback path is coupled between the output node and the active pull down portion of the driver circuit. The feedback path controls the activation of the pull down portion of the driver circuit.
