MEMORY UNIT, MEMORY AND CONTROL METHOD FOR THE MEMORY UNIT

摘要

Embodiments of the present invention disclose a storage unit, a memory, and a method for controlling a storage unit, to increase storage density, and reduce power consumption and production costs. The storage unit includes: a comb-shaped magnetic track, a first drive circuit, a second drive circuit, a first drive port, and a second drive port, where the comb-shaped magnetic track includes a first storage area, a second storage area, and a comb handle, and the first storage area and the second storage area include more than two memory bars; by controlling input voltages of a first port, a second port, the first drive port, and the second drive port and driving the first drive circuit, a current pulse is generated in a memory bar in the first storage area, and a magnetic domain 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 a memory bar in the second storage area, and a magnetic domain is driven to move.
