    Abstract: Methods, systems, and devices for memory cell selection to enable a memory device to select a targeted memory cell during a write operation are described. The memory device may apply a first pulse to a selected bit line of the targeted memory cell while applying a voltage to deselected word lines to prevent current leakage. If the targeted memory is not selected after the first pulse, the memory device may apply a second pulse to the selected bit line while applying a voltage to the deselected word lines. If the targeted memory cell is not selected following the second pulse, the memory device may apply a third pulse to the selected bit line while applying the voltage to the deselected word lines. The memory device may detect a snapback event after any of the pulses if the targeted memory cell is selected.
