Boise State University Theses and Dissertations
Chalcogenide based non-volatile Phase Change Memory (PCM) circuits were designed to investigate new emerging non-volatile memory technologies. An overview of the operation of chalcogenide-based resistive PCM for circuit designers is presented. MOSIS fabrication service was used along with Idaho Microfabrication Lab at Boise State University to develop PCM chips. Experimental results show successful integration of two discreet processing services for developing chalcogenide based non-volatile memory circuits. Possible multi-state capabilities were observed during the testing of single memory bits.
Four Delta Sigma Modulation (DSM) based sensing techniques for resistive memory are presented. The proposed sensing techniques have the advantage over traditional …
