    摘要: An improved phase change memory device has a phase change structure including a thin part between a contact surface of an electrode and a dielectric structure. For example, the thin part has a maximum thickness that is smaller than a maximum width of the contact surface of the electrode. In another example, the phase change structure surrounds the dielectric structure. Several variations improve the contact between the phase change structure and an electrode.

    摘要: A 3D memory device includes bottom and top memory cubes having respective arrays of vertical NAND string structures. A common source plane comprising a layer of conductive material is between the top and bottom memory cubes. The source plane is supplied a bias voltage such as ground, and is selectively coupled to an end of the vertical NAND string structures of the bottom and top memory cubes. Memory cells in a particular memory cube are read using current through the particular vertical NAND string between the source plane and a corresponding bit line coupled to another end of the particular vertical NAND string.

    摘要: An integrated circuit memory is based on isolation device free memory cells. The memory cells are passively coupled to bit lines and word lines. The memory cells include an anti-fuse element and an element of phase change material in series. A rupture filament through the anti-fuse layer acts as an electrode for the phase change element. Control circuitry is configured to apply bias arrangements for operation of the memory cells, including a first write bias arrangement to induce a volume of the higher resistivity phase in the phase change material establishing a first threshold for the selected memory cell below a read threshold, a second write bias arrangement to induce a larger volume of the higher resistivity phase in phase change material establishing a second threshold for the selected memory cell above the read threshold, and a read bias arrangement to apply the read threshold to the selected memory cell.
