  • Publication number: 20220382465
    Abstract: Systems, apparatuses and methods may provide for technology that determines a write-to-write delay with respect to a memory cell, wherein one or more neighboring cells are adjacent to the memory cell and controls a write disturb refresh rate of the one or more neighboring cells based on the write-to-write delay. In one example, the technology increments a write counter corresponding to the memory cell by a first value if the write-to-write delay exceeds a delay threshold and increments the write counter by a second value if the write-to-write delay does not exceed the delay threshold, wherein the second value is greater than the first value, and wherein the write disturb refresh rate is controlled based on the write counter.

  • Publication number: 20160372193
    Abstract: Embodiments of the present disclosure describe read and write operations in phase change memory to reduce snapback disturb. In an embodiment, an apparatus includes read circuitry to apply a read voltage to a phase change memory (PCM) cell, setback circuitry to apply a setback pulse to the PCM cell in response to the application of the read voltage, wherein the setback pulse is a shorter set pulse performed for a first period of time that is shorter than a second period of time for a regular set pulse that is configured to transition the PCM cell from an amorphous state to a crystalline state, sense circuitry to sense, concurrently with application of the setback pulse, whether the PCM cell is in the amorphous state or the crystalline state. Other embodiments may be described and/or claimed.

  • Patent number: 9384801
    Abstract: Embodiments including systems, methods, and apparatuses associated with expanding a threshold voltage window of memory cells are described herein. Specifically, in some embodiments memory cells may be configured to store data by being set to a set state or a reset state. In some embodiments, a dummy-read process may be performed on memory cells in the set state prior to a read process. In some embodiments, a modified reset algorithm may be performed on memory cells in the reset state. Other embodiments may be described or claimed.
