    摘要： A memory array includes a plurality of memory cells, each of which receives a bit line, a first word line, and a second word line. Each memory cell includes a cell selection circuit, which allows the memory cell to be selected. Each memory cell also includes a two-terminal switching device, which includes first and second conductive terminals in electrical communication with a nanotube article. The memory array also includes a memory operation circuit, which is operably coupled to the bit line, the first word line, and the second word line of each cell. The circuit can select the cell by activating an appropriate line, and can apply appropriate electrical stimuli to an appropriate line to reprogrammably change the relative resistance of the nanotube article between the first and second terminals. The relative resistance corresponds to an informational state of the memory cell.

    摘要： Under one aspect, a memory array includes word lines; bit lines; memory cells; and a memory operation circuit. Each memory cell responds to electrical stimulus on a word line and on a bit line and includes: a two-terminal non-volatile nanotube switching device having first and second terminals, a semiconductor diode element, and a nanotube fabric article capable of multiple resistance states. The semiconductor diode and nanotube article are between and in electrical communication with the first and second terminals, which are coupled to the word line bit line respectively. The operation circuit selects cells by activating bit and/or word lines, detects a resistance state of the nanotube fabric article of a selected memory cell, and adjusts electrical stimulus applied to the cell to controllably induce a selected resistance state in the nanotube fabric article. The selected resistance state corresponds to an informational state of the memory cell.
