  • Resetting Phase Change Memory Bits
    Publication number: 20130051139
    Abstract: After determining that a reset pulse has reached its programmed threshold voltage level, a lower voltage verify can be conducted. This can be followed by another program step to increase the programmed threshold voltage. By avoiding the need for subsequent verification after the cell has reached its desired threshold level, read disturbs may be reduced in some embodiments. In some embodiments, by using lower voltages, it is not necessary to apply higher bias voltages to de-selected cells which may result in current leakage.
    Type: Application
