摘要： An integrated circuit phase change memory can be pre-coded by inducing a first resistance state in some cells and the memory, and a second resistance state and some other cells in the memory to represent a data set. The integrated circuit phase change memory is mounted on a substrate after coding the data set. After mounting the integrated circuit phase change memory, the data set is read by sensing the first and second resistance states, and changing cells in the first resistance state to a third resistance state and changing cells in the second resistance state to a fourth resistance state. The first and second resistance states maintain a sensing margin after solder bonding or other thermal cycling process. The third and fourth resistance states are characterized by the ability to cause a transition using higher speed and lower power, suitable for a mission function of a circuit.

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： A method for manufacturing a memory device, and a resulting device, is described using silicon oxide doped chalcogenide material. A first electrode having a contact surface; a body of phase change memory material in a polycrystalline state including a portion in contact with the contact surface of the first electrode, and a second electrode in contact with the body of phase change material are formed. The process includes melting and cooling the phase change memory material one or more times within an active region in the body of phase change material without disturbing the polycrystalline state outside the active region. A mesh of silicon oxide in the active region with at least one domain of chalcogenide material results. Also, the grain size of the phase change material in the polycrystalline state outside the active region is small, resulting in a more uniform structure.

摘要： A memory cell array of dielectric charge trapping memory cells and method for performing program, read and erase operations on the memory cell array that includes bits stored at charge trapping sites in adjacent memory cells. A bit of information is stored at a first charge trapping site in a first memory cell and a second charge trapping site in a second adjacent memory cell. Storing charge at two trapping sites in adjacent memory cells increases data retention rates of the array of memory cells as each charge trapping site can be read to represent the data that is stored at the data site. Each corresponding charge trapping site can be read independently and in parallel so that the results can be compared to determine the data value that is stored at the data site in an array of dielectric charge trapping memory cells.
