Abstract
Chalcogenide-based nanowire memories are implemented using a variety of methods and devices. According to an example embodiment of the present invention, a method of manufacturing a memory circuit is implemented. The method includes depositing nanoparticles at locations on a substrate. Chalcogenide-based nanowires are created at the locations on the substrate using a vapor-liquid-solid technique. Insulating material is deposited between the chalcogenide-based nanowires. Lines are created to connect at least some of the chalcogenide-based nanowires.
Claims15
A chalcogenide-based memory device comprising:
- chalcogenide-based nanowires;
- a layer, between the chalcogenide-based nanowires, to provide at least some insulation therebetween;
- a line electrically connected to at least some of the chalcogenide-based nanowires;
- and
- a control circuit to control and to communicatively couple to at least one of the chalcogenide-based nanowires for accessing data.
A memory device comprising:
- means, including chalcogenide-based nanowires, for providing access to data, for providing at least some insulation between the chalcogenide-based nanowires, and for interconnecting to at least some of the chalcogenide-based nanowires;
- and
- means for controlling and for communicatively coupling to the chalcogenide-based nanowires.
For use with a phase-change memory device having chalcogenide-based nanowires, a method comprising:
- impeding heat or electricity transfer between the chalcogenide-based nanowires using an insulating layer;
- heating at least one of the chalcogenide-based nanowires to store data;
- and
- reading stored data from at least one of the chalcogenide-based nanowires using a line electrically connected to at least some of the chalcogenide-based nanowires.
