    摘要: A memory cell includes a first electrode, a second electrode, and a first portion of phase-change material contacting the first electrode. The memory cell includes a second portion of phase-change material contacting the second electrode and a third portion of phase-change material between the first portion and the second portion. A phase-change material composition of the third portion and the second portion gradually transitions from the third portion to the second portion.

    摘要: An integrated circuit includes an array of resistance changing memory cells. The array includes a first portion. The integrated circuit includes a circuit configured to apply a set pulse having a first pulse width to a first memory cell in the first portion to set the first memory cell. The first pulse width is based on a predetermined error percentage for the first portion.

    摘要: According to one embodiment of the present invention, a method of operating an integrated circuit including a plurality of resistance changing memory cells grouped into physical memory units is provided. The method includes: Monitoring writing access numbers assigned to the physical memory units, each writing access number reflecting the number of writing accesses to the physical memory unit to which the writing access number is assigned; if the value of a writing access number assigned to a first physical memory unit exceeds a writing access threshold value, a data exchange process is carried out during which the data content stored within the first physical memory unit is exchanged with the data content of a second physical memory unit having a writing access number of a lower value.
