    Abstract: Fabrication of a magnetoresistive device, comprising a magnetically fixed region (40) on at least one seed region (20, 25) on an electrically conductive region (15), involves forming a seed region (20'; 21), treating the seed region by exposing a surface thereof to a gas, such as oxygen, and optionally forming a second seed region (22) thereon. Alternatively, a gas, such as oxygen or nitrogen, or one or more atomic elements, such as boron or carbon, may be added during (sputter) deposition of the seed region (25).

    Abstract: Fabrication of a magnetic memory element, including a via (125) in an interlevel dielectric layer (120), providing an electrical connection between an underlying metal region (110) and a magnetoresistive stack device, such as a magnetic tunnel junction (150), involves forming a transition metal layer (130) in the via by atomic layer deposition. The via optionally includes a tantalum-rich layer (140) above, and/or a cap layer (115) below, the transition metal layer, and may have a diameter less than or equal than a diameter of the magnetoresistive stack device.

    Abstract: A memory having a delayed write-back to the array of data corresponding to a previously opened page allows delays associated with write-back operations to be avoided. After an initial activation opens a first page and the read/write operations for that page are complete, write-back of the open page to the array of memory cells is delayed until after completion of a subsequent activate operation that opens a new page. Techniques to force a write-back in the absence of another activate operation are also disclosed.

    Abstract translation: 具有延迟回写到对应于先前打开的页面的数据阵列的存储器允许避免与回写操作相关联的延迟。 在初始激活打开第一页并且该页的读取/写入操作完成之后,打开页面回写到存储器单元阵列被延迟直到完成后续激活操作(打开新页面)之后。 还公开了在没有另一个激活操作的情况下强制回写的技术。

    Abstract: In some examples, a memory device may be configured to store data in either an original or an inverted state based at least in part on a state associated with one or more shorted bit cells. For instance, the memory device may be configured to identify a shorted bit cell within a memory array and to store the data in the memory array, such that a state of the data bit stored in the shorted bit cell matches the state associated with the shorted bit cell.

    Abstract: In some examples, a memory device includes memory arrays configured to store pages of data organized into multiple ECC words. The memory device also includes at least one input/output pad for each ECC word associated with a page, such that a first level of error correction may be performed by the memory device on each of the ECC words associated with a page and a second level of error correction may be perform. ed on the data output by each of the input/output pads during a particular period of time. Each of the one or more input/output pads of the memory device may be configured to provide only one bit of data per ECC word to an external source during an access from an external source.
