STORAGE UNIT, MEMORY AND STORAGE UNIT CONTROL METHOD

摘要

Embodiments of the present invention provide a storage unit, a memory, and a method for controlling a storage unit, to increase storage density and reduce power consumption. The storage unit includes: a U-shaped magnetic track, a first drive circuit, a second drive circuit, a first drive port, and a second drive port, where the U-shaped magnetic track includes a first port, a second port, a first storage area, and a second storage area; the first drive circuit is configured to drive the first storage area, and the second drive circuit is configured to drive the second storage area; by controlling input voltages of the first port, the second port, the first drive port, and the second drive port and driving the first drive circuit, a current pulse is generated in the first storage area, and a magnetic domain in the first storage area is driven to move; and by controlling the input voltages of the first port, the second port, the first drive port, and the second drive port and driving the second drive circuit, a current pulse is generated in the second storage area, and a magnetic domain in the second storage area is driven to move.
