    摘要: The control circuit performs a reset operation and a set operation that change the resistance states of phase change memory cells of the array. The control circuit changes at least one parameter, of at least one of the reset operation and the set operation for future operations. This change is responsive to an indicator of degraded memory state retention of the array.

    摘要: A non-volatile VG memory array employing memory semiconductor cells capable of storing two bits of information having a non-conducting charge trapping dielectric, such as silicon nitride, layered in associating with at least one electrical insulating layer, such as an oxide, is disclosed. Bit lines of the memory array are capable of transmitting positive voltage to reach the source/drain regions of the memory cells of the array. A method that includes the hole injection erasure of the memory cells of the array that lowers the voltage threshold of the memory cells to a value lower than the initial voltage threshold of the cells is disclosed. The hole injection induced lower voltage threshold reduces the second bit effect such that the window of operation between the programmed and un-programmed voltage thresholds of the bits is widened. The programming and read steps reduce leakage current of the memory cells in the array.

    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.
