    Abstract: Methods, systems, devices, and other implementations to store fuse data in memory devices are described. Some implementations may include an array of memory cells with different portions of cells for storing data. A first portion of the array may store fuse data and may contain a chalcogenide storage element, while a second portion of the array may store user data. Sense circuitry may be coupled with the array, and may determine the value of the fuse data using various signaling techniques. In some cases, the sense circuitry may implement differential storage and differential signaling to determine the value of the fuse data stored in the first portion of the array.

    Abstract: Methods, systems, and devices for operating memory cell(s) are described. A resistance of a storage element included in a memory cell may be programmed by applying a voltage to the memory cell that causes ion movement within the storage element, where the storage element remains in a single phase and has different resistivity based on a location of the ions within the storage element. In some cases, multiple of such storage elements may be included in a memory cell, where ions within the storage elements respond differently to electric pulses, and a non-binary logic value may be stored in the memory cell by applying a series of voltages or currents to the memory cell.

    Abstract: Some embodiments include memory arrays having a plurality of memory cells vertically between bitlines and wordlines. The memory cells contain phase change material. Heat shields are laterally between immediately adjacent memory cells along a bitline direction. The heat shields contain electrically conductive material and are electrically connected with the bitlines. Some embodiments include memory arrays having a plurality of memory cells arranged in a first grid. The first grid has columns along a first direction and has rows along a second direction substantially orthogonal to the first direction. First heat shields are between adjacent memory cells along the first direction and are arranged in a second grid offset from the first grid along the first direction. Second heat shields are between adjacent memory cells along the second direction, and are arranged lines in lines extending along the first direction. Some embodiments include methods for forming memory arrays.

    Abstract: Methods, systems, and devices for pulse based multi-level cell programming are described. A memory device may identify an intermediate logic state to store to a multi-level memory cell capable of storing three or more logic states. The memory device may apply a first pulse with a first polarity to the memory cell to store a SET or RESET state to the memory cell based on identifying the intermediate logic state. As such, the memory device may identify a threshold voltage of the memory cell that stores the SET or RESET state. The memory device may apply a quantity of pulses to the memory cell to store the identified intermediate logic state based on identifying the threshold voltage of the memory cell that stores the SET or RESET state. In some examples, the quantity of pulses may have a second polarity different than the first polarity.
