Abstract
An apparatus including a Correlated Electron Switch (CES) element and a programing circuit is provided. The programing circuit provides a programing signal to the CES element to program the CES element to an impedance state of multiple impedance states when a number of times the CES element has been programed is less than a threshold.
Claims21
An apparatus comprising:
- a Correlated Electron Switch (CES) element comprising correlated electron material (CEM);
- and
- a programing circuit configured to:
- provide a programing signal to the CES element to program the CES element to an impedance state of a plurality of impedance states, the plurality of impedance states being based, at least in part, on a concentration of electron holes in the CEM, when a number of times the CES element has been programed is less than a threshold number of times.
1 more element
A method comprising:
- determining a threshold programing number of times for a Correlated Electron Switch (CES) element comprising correlated electron material (CEM);
- retrieving a count indicative of a number of times the CES element has been programed;
- determining if the count is less than the threshold number of times;
- and
- providing a programing signal to the CES element, responsive to determining the count is less than the threshold number of times, to program the CES element to an impedance state of a plurality of impedance states, the plurality of impedance states being based, at least in part, on a concentration of electron holes in the CEM.
2 more elements
An apparatus comprising:
- a plurality of Correlated Electron Switch (CES) elements, wherein each CES element comprises correlated electron material (CEM) in a first impedance state of a plurality of impedance states, the plurality of impedance states being based, at least in part, on a concentration of electron holes in the CEM;
- and
- a plurality of connection pads, each connection pad being coupled to at least one CES element of the plurality of CES elements and configured to receive a programing signal for the at least one CES element to program the at least one CES element to a desired impedance state when a number of times the at least one CES element has been programed is less than a threshold number of times, the threshold number of times being at least two.
