Patent ID: 8228706

Claim:
A memory cell, comprising: at least two chains of magnetic columns, wherein at least one of the at least two chains of magnetic columns is oriented in a bit-line direction relative to at least another of the at least two chains of magnetic columns, wherein each of the at least two chains of magnetic columns comprises: a plurality of magnetic columns, each of the plurality of magnetic columns comprising a plurality of magnetic domains, wherein the plurality of magnetic columns is electrically connected along a dimension of the memory cell to create a path that moves the plurality of magnetic domains up and down the plurality of magnetic columns in an alternating manner; at least one reader coupled to the at least two chains of magnetic columns, for reading data from the plurality of magnetic domains in each of the at least two chains of magnetic columns; a temporary memory for storing the data; and at least one writer coupled to the at least two chains of magnetic columns, for writing the data in the temporary memory to the plurality of magnetic domains in each of the at least two chains of magnetic columns.
