Abstract
In a memory array having a plurality of bitlines each connected to a plurality of memory devices having a state in which current is transferred by the memory device and a state in which current is not transferred by the device, a column select device for activating each bitline, a plurality of wordlines for activating individual memory devices joined to each bitline, apparatus for providing constant current in the conducting state of a memory device connected to a bitline, a device connecting a source voltage to a plurality of bitlines, and a reference bitline for providing an output reference signal, the improvement including apparatus for providing a source of current in addition to current through the device connecting a source voltage to a plurality of bitlines in order to charge any capacitance of a selected bitline when that bitline is selected whereby switching between memory devices joined to different bitlines is accelerated.
