CONDUCTIVE-POLYMER ELECTRONIC SWITCH

Title:

CONDUCTIVE-POLYMER ELECTRONIC SWITCH

Document Type and Number:

WIPO Patent Application WO2004070566

Kind Code:

A3

Abstract:

A switch, used as an electronic-memory element, comprising a conductive organic polymer layer (819) sandwiched between, and in contact with, two metallic conductive elements (802-806 and 810-813). In an initial post-fabrication state, the organic polymer layer is relatively highly conductive, the post-fabrication constituting a first stable state of the memory element that can serve to represent a binary bit "1" or "0," depending on which of two possible encoding conventions is employed. A relatively high voltage pulse can be passed between the two metal conductive elements, resulting in a market decrease in the current-carrying capacity of the organic polymer layer sandwiched between the two conductive elements. This change in conductivity of the organic polymer layer is generally irreversible, and constitutes a second stable state of the memory element that may be used to encode a binary bit "0" or "1". Organic-polymer-based memory elements, modified to include an additional diode-acting layer (818), may be fabricated in dense, two-dimensional arrays.
