Abstract
Subject matter disclosed herein may relate to correlated electron switches that are capable of asymmetric set or reset operations.
Claims12
A correlated electron switch (CES) device comprising:
- first and second terminals;
- and
- a portion of a correlated electron material (CEM) substrate coupled between the first and second terminals, wherein the CEM substrate is non-uniformly doped between the first and second terminals, and at least a portion of the CEM substrate intrinsic,
- wherein the CES is capable of being placed in a conductive or low impedance state responsive to a first or second set operation, or an insulative or high impedance memory state responsive to a first or second reset operation, and
- wherein the first set operation is asymmetric with the second set operation.
2 more elements
A method comprising:
- forming first and second terminals on at least a portion of a correlated electron material (CEM) substrate to form a correlated electron switch (CES), wherein the CES is capable of being placed in a conductive or low impedance state responsive to a first or second set operation, or an insulative or high impedance memory state responsive to a first or second reset operation;
- maintaining at least a portion of the CEM substrate intrinsic;
- and
- affecting a structure or composition of the CEM substrate such that the first set operation is asymmetric with the second set operation by applying a P-type doping or an N-type doping over at least a portion of the CEM substrate.
1 more element
The method of 8, wherein the CEM substrate comprises a transition metal oxide.
