Classification: CPC H  G | IPC G  H

Claim 14:
15. A memory device, comprising:
a plurality of active areas extending along a first direction;
a plurality of gate electrodes extending along a second direction perpendicular to the first direction; and
a unit cell located at an intersection of a respective active area and a respective gate electrode, wherein the unit cell comprises a transistor and a memory cell over the transistor,
wherein the memory cell includes: a selector, a magnetic tunnel junction (MTJ) structure over the selector, and a spin orbit torque (SOT) layer between the selector and the MTJ structure,
wherein the unit cell has a length along the second direction and a width along the first direction, the length is approximately within a range of two adjacent active areas, the width is approximately within a range of three adjacent gate electrodes, and the SOT layer has a length extending from one transistor to overlay adjacent transistor.
