Abstract:
One or more control lines other than those used to activate a non-volatile memory cell may be used to sense a data value of the cell. For example, an apparatus may include a selection circuit that selects, based on an address corresponding to a non-volatile memory cell included an array of non-volatile memory cells, a word line coupled to the non-volatile memory cells to activate the non-volatile memory cell. An amplifier circuit may sense a data value stored in the non-volatile memory cell based on a sense signal having a voltage level based on voltage levels of one or more other word lines of the array of non-volatile memory cells. In another example, a data value of a non-volatile memory cell coupled to a word line may be sensed based on the voltage levels of one or more dummy sense lines within the array.
