Abstract
An apparatus including a volume of phase change material disposed between a first conductor and a second conductor on a substrate, and a plurality of electrodes coupled to the volume of phase change material and the first conductor. A method including introducing, over a first conductor on a substrate, a plurality of electrodes coupled to the first conductor, introducing a phase change material over the plurality of electrodes and in electrical communication with the plurality of electrodes, and introducing a second conductor over the phase change material and coupled to the phase change material.
Claims17
An apparatus comprising:
- a volume of phase change material disposed between a first conductor and a second conductor on a substrate;
- and
- a plurality of electrodes coupled to the volume of phase change material and the first conductor.
An apparatus comprising:
- a first conductor;
- a second conductor over the substrate and electrically isolated from the first conductor;
- a volume of phase change material over the substrate and disposed contiguous with the second conductor;
- and
- a plurality of electrodes coupled between the first conductor and the phase change material.
An apparatus comprising:
- a matrix of M conductors and N conductors over a substrate, wherein M and N are each greater than one;
- a plurality of electrodes coupled to a first plurality of conductors, M1 through Mn;
- and
- a phase change material, PC1, coupled to a first N conductor, N1, and the plurality of electrodes, wherein a volume of the PC1 adjacent the area of coupling of an electrode is settable to one of at least two resistivity values in response to current through a first conductor and a second conductor.
A method comprising:
- introducing, over a first conductor on a substrate, a plurality of electrodes coupled to the first conductor;
- introducing a phase change material over the plurality of electrodes and in electrical communication with the plurality of electrodes;
- and
- introducing a second conductor over the phase change material and coupled to the phase change material.
