    摘要: A 3D array of nonvolatile memory has each read/write element accessed at a crossing between a word line and a bit line. The read/write element forms a tubular electrode having an outside shell of R/W material enclosing an oxide core. In a rectangular form, one side of the electrode contacts the word line and another side contacts the bit line. The thickness of the shell rather than its surface areas in contact with the word line and bit line determines the conduction cross-section and therefore the resistance. By adjusting the thickness of the shell, independent of its contact area with either the word line or bit line, each read/write element can operate with a much increased resistance and therefore much reduced current. Processes to manufacture a 3D array with such tubular R/W elements 3D array are also described.

    摘要: A three-dimensional nonvolatile memory array includes a select layer that selectively connects vertical bit lines to horizontal bit lines. Individual select switches of the select layer include two separately controllable transistors that are connected in series between a horizontal bit line and a vertical bit line. Each transistor in a select switch is connected to a different control circuit by a different select line.
