摘要:
The present invention can provide a magnetic memory structure comprising a column comprising a plurality of layers of magnetic material, each sized to adopt a single magnetic domain state, and a plurality of layers of non-magnetic material arranged as spacer layers between adjacent ones of the layers of magnetic material, such that successive magnetic layers in the column are magnetically antiparallel coupled. The column is arranged to maintain therein a plurality of stable transitions of an order parameter of the magnetisations between the magnetic layers, the transitions having a chirality. This enables a single magnetic column structure to store multiple data bits in such a way as to enable the bits to be propagated through the column to enable sequential reading and/or writing of data in the column.
摘要(中):
本发明可以提供一种磁存储结构,该磁存储器结构包括一列,该柱包括多个磁性材料层,每个磁性材料层的尺寸应采用单一磁畴状态,多层非磁性材料层被布置为相邻的一部分之间的间隔层 磁性材料层,使得列中的连续磁性层磁性反平行耦合。 该列被布置成在其中维持磁性层之间的磁化的阶数参数的多个稳定转变,该转变具有手性。 这使得单个磁柱结构能够存储多个数据位,使得这些位能够通过列传播,以使得能够在列中顺序读取和/或写入数据。
