Abstract:
1. A method for operating a non-volatile storage system, comprising: setting a plurality of word lines associated with a memory array to an unselected voltage, the memory array comprises a cross-point memory array including a plurality of rewriteable non-volatile memory cells; setting a plurality of bit lines associated with the memory array to the unselected voltage; determining a selected bit line of the plurality of bit lines and a plurality of unselected bit lines of the plurality of bit lines; determining a selected word line of the plurality of word lines and a plurality of unselected word lines of the plurality of word lines; floating the plurality of unselected bit lines subsequent to the setting a plurality of bit lines associated with the memory array to the unselected voltage; setting the selected bit line to a selected bit line voltage; setting the selected word line to a read voltage greater than the selected bit line voltage; determining a state of a memory cell connected to the selected word line and the selected bit line while setting the selected word line to the read voltage and floating the plurality of unselected bit lines; and outputting the state of the memory cell.
