  • Patent number: 9036409
    Abstract: Disturb from the reset to the set state may be reduced by creating an amorphous phase that is substantially free of crystal nuclei when programming the reset state in a phase change memory. In some embodiments, this can be achieved by using a current or a voltage to program that exceeds the threshold voltage of the phase change memory element, but does not exceed a safe current voltage which would cause a disturb.

  • Patent number: 8345472
    Abstract: A three-terminal Ovonic Threshold Switch (OTS) is used to provide current to a Phase Change Memory Switch (PCMS) cross point array. The current is started by sending a small current into the second terminal of the three-terminal OTS allowing a larger current to flow from the first terminal to the third terminal of the three-terminal OTS. A method of making the three-terminal OTS is also presented.
