Selector Threshold Compensation

An apparatus, comprising:

• a charge accumulator in electronic communication with a memory cell, the charge accumulator configured to detect current flow through the memory cell;
• a comparator in electronic communication with the memory cell and the charge accumulator, the comparator configured to indicate that a threshold voltage of the memory cell has been reached based at least in part on an output of the charge accumulator;
• a switch controller in electronic communication with the comparator, the switch controller configured to apply a second voltage to the memory cell based at least in part on an indication from the comparator;
• and
• a signal generator in electronic communication with the memory cell and the switch controller, the signal generator configured to apply a first voltage to the memory cell based at least in part on an output of the switch controller.

An apparatus comprising:

• a memory cell;
• a comparator in electronic communication with the memory cell;
• and
• a controller in electronic communication with the memory cell and the comparator, wherein the controller is operable to:
• initialize the comparator to sense whether a threshold voltage of the memory cell has been reached;
• and
• reinitialize the comparator, to sense a logic state stored by the memory cell based at least in part on the threshold voltage being reached.
