  • Method of resetting phase change memory bits through a series of pulses of increasing amplitude
    Publication number: 20080062754
    Abstract: A set bit in a phase change memory may be programmed to a reset bit using a series of pulses of increasing amplitude. An initial start pulse is applied. After the start pulse is applied, a check determines whether the bit has been reset. If not, a higher amplitude pulse is applied. Each time the pulse amplitude is to be incremented, a check determines whether a maximum safe pulse amplitude has been exceeded. The pulse amplitude is continually incremented until either the maximum is reached or all the bits to be programmed have been programmed into the correct reset state.

  • Controlling the location of conduction breakdown in phase change memories
    Publication number: 20050032319
    Abstract: A phase change memory may be formed in a pore of a semiconductor structure. A selected region of the pore may be processed so that breakdown in that region is either more or less likely. As a result, by reducing the variation in the location of breakdown from cell to cell and memory to memory, greater consistency can be achieved.
