dc.description.abstract | This dissertation addresses the scaling limitations of the Phase Change Random Access Memory (PCRAM) that is considered as one of the best candidates for meeting the scaling requirements for the next wave of memory technologies. Firstly, a new classification of the scalability limitations of PCRAM, including the lithography technology, the physical limitations of materials in PCRAM, the thermal-cross talk among memory cells and the current limitation of memory cells. Particular emphasis is paid to the physical limitations of the materials and the current limitation of memory cells in the thesis. To study physical limitation of the materials, a new classification of the phase change based on different interface environment is proposed. Limitations based on this classification are studied. For current limitation of memory cells, superlattice-like (SLL) PCRAM is designed, fabricated and tested. Fifty percent current reduction is demonstrated by 128-bit test chip. | |
