Abstract
A selector for a memory cell in a memory array may operate by opening different conductive paths to high and low voltages during set and reset operations. A first transistor may open a conductive path between a high voltage and a terminal of the memory element during a reset operation. Similarly, a second transistor may open a conductive path between a low voltage and the terminal of the memory element during a set operation. Some implementations may add a third transistor in series with the first transistor and a fourth transistor in series with the second transistor. The gates of the third and fourth transistors may be biased at a voltage that is about halfway between the low and high voltages. This selector may use smaller transistors while still facilitating high-voltage set and reset operations on resistive memory elements.
