Abstract:
1. A memory cell comprising: a first electrode; a second electrode; a dielectric located between the first and second electrodes and configured to allow the memory cell to form a conductive path in the dielectric from a portion of a material of the first electrode to represent a first value of information stored in the memory cell and configured to allow the memory cell to break the conductive path to represent a second value of information stored in the memory cell; and an access component between the dielectric and the second electrode, the access component configured to turn on when a first voltage difference in a first direction across the first and second electrodes exceeds a first voltage value and to turn on when a second voltage difference in a second direction across the first and second electrodes exceeds a second voltage value, wherein no portion of the access component is between portions of the dielectric.
