    Abstract: A memory decoder enables the selection of a conductor of a row or column of a crosspoint array memory. The decoder includes a circuit to apply a bias voltage to select or deselect the conductor. The conductor can be either a wordline or a bitline. The decoder also includes a select device to selectively provide both high voltage bias and low voltage bias to the circuit to enable the circuit to apply the bias voltage. Thus, a single end device provides either rail to the bias circuit.

    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.
