Abstract

The present invention discloses a memory device (100), such as a PCRAM, and a method of forming such a memory device, the memory device comprising a chalcogenide glass aggregate, wherein germanium telluride glass (18) and a metal such as tin selenide— Chalcogenide (20) contacts.

Description

[0001] This application is a continuation-in-part of U.S. Patent Application No. 10 / 916,421, filed August 12, 2004, entitled PCRAM Device With Switching Glass Layer, and is also a continuation-in-part of U.S. Patent Application No. Continuation-in-Part of US Patent Application Serial No. 10 / 893,299 for Memory Device and Method of Fabrication. Each of these applications is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to the field of random access memory (RAM) devices formed using resistance variable materials. Background technique [0003] Resistance variable memory elements, including programmable conductive random access memory (PCRAM) elements, have been investigated for suitability as semi-volatile and non-volatile random access memory devices. In a typical PCRAM device, the resistance of the chalcogenide glass backbone can be programmed to stable lower conductivity (ie, higher resistance) and higher conductivit...
