Abstract | A method, apparatus and system to address memory cells in a memory array that includes address lines comprising wordlines (WLs) and bitlines (BLs). The method comprises: controlling a decoder circuitry of a memory array, the memory array including a plurality of WLs and a plurality of BLs, the decoder circuitry including a plurality of switches coupled respectively to the WLs, or respectively to the BLs; and causing a selected switch of the plurality of switches to change a bias of a corresponding selected address line coupled thereto from a floating bias at an idle state of the decoder circuitry to either a positive bias or a negative bias without changing a bias at deselected address lines corresponding to deselected switches of the plurality of switches from the floating bias at the idle state. |
