  • Publication number: 20240006011
    Abstract: The present disclosure is drawn to, among other things, a method of managing a memory device. In some aspects, the method includes determining whether a first address for a page in a first memory region is mapped in a map table, setting a target address as a second address identified in the map table as being mapped to the first address, setting the target address as the first address, determining a number of bits that fail in each word of a plurality of first-layer error correction code (ECC) words for the target address, and adding the target address to the map table, writing-back contents from the target address to a repair address in the first memory region, and updating the map table by mapping the target address to the repair address.

  • Patent number: 11264564
    Abstract: A magnetoresistive device may include one or more electrodes or electrically conductive lines and a fixed region and a free region disposed between the electrodes or electrically conductive lines. The fixed region may have a fixed magnetic state and the free region may be configured to have a first magnetic state and a second magnetic state. The free region may store a first value when in the first magnetic state and store a second value when in the second magnetic state. The magnetoresistive device may further include a dielectric layer between the free region and the fixed region and a spin-Hall (SH) material proximate to at least a portion of the free region. An insertion layer may be disposed between the SH material and the free region.

  • Patent number: 10431733
    Abstract: A perpendicular magnetic tunnel junction device (pMTJ) is provided that has a structure of a first heavy metal layer, a first thin dusting layer on the first heavy metal layer, a first CoFeB layer on the thin dusting layer, a MgO barrier layer on the first CoFeB layer, a second CoFeB layer on the MgO barrier layer, a second thin dusting layer on the CoFeB layer; and a second heavy metal layer on the thin dusting layer. The insertion of the thin dusting layer improves thermal stability of the pMTJ structure.
