Abstract:
1. A method for reading data from a memory array, comprising: applying a read voltage to one of a plurality of first conductive array lines; applying a bias signal generated by a bias element to a remainder of the plurality of first conductive array lines; applying, using a switch, a pre-charge voltage to a plurality of second conductive array lines; disconnecting, using the switch, the pre-charge voltage from the plurality of second conductive array lines; connecting, using the switch, a floating voltage potential to the plurality of second conductive array lines after the disconnecting; sensing a current flowing through each of the plurality of second conductive array lines; comparing the current flowing through each of the plurality of second conductive array lines with at least one reference signal; and generating read data for each of the plurality of second conductive array lines based on the comparing.
