ABSTRACT:
A programmable read only memory device according to the present invention comprises a plurality of row selector blocks respectively coupled between row lines and a ground node, and each row selector block has a first discharging unit providing a current path in a read-out mode of operation only and a second discharging unit providing a current path in both write-in and read out modes of operation, so that the current driving capability is decreased in the read out mode of operation, thereby decreasing the current consumption as well as the time period consumed for a single read out operation.
