    摘要: Methods are provided for operating a magnetic random access memory device including a memory cell having a magnetic tunnel junction structure on a substrate. In particular, a writing current pulse may be provided through the magnetic tunnel junction structure, and a writing magnetic field pulse may be provided through the magnetic tunnel junction structure. In addition, at least a portion of the writing magnetic field pulse may be overlapping in time with respect to at least a portion of the writing current pulse, and at least a portion of the writing current pulse and/or at least a portion of the writing magnetic field pulse may be non-overlapping in time with respect to the other. Related devices are also discussed.

    摘要: A number of read cycles applied to a selected memory location of a memory device, such as a variable-resistance memory device, is monitored. Write data to be written to the selected memory location is received. Selective pre-write verifying and writing of the received write data to the selected memory location occurs based on the monitored number of read cycles. Selectively pre-write verifying and writing of the received write data may include, for example, writing received write data to the selected memory cell region without pre-write verification responsive to the monitored number of read cycles being greater than a predetermined number of read cycles

    摘要: Magnetic RAM cells have split sub-digit lines surrounded by cladding layers and methods of fabricating the same are provided. The magnetic RAM cells include first and second sub-digit lines formed over a semiconductor substrate. Only a bottom surface and an outer sidewall of the first sub-digit line are covered with a first cladding layer pattern. In addition, only a bottom surface and an outer sidewall of the second sub-digit line are covered with a second cladding layer pattern. The outer sidewall of the first sub-digit line is located distal from the second sub-digit line and the outer sidewall of the second sub-digit line is located distal the first sub-digit line. Methods of fabricating the magnetic RAM cells are also provided.
