Abstract:
The present invention relates to a magnetic RAM including a memory cell, the memory cell including a metal layer, a magnetic tunnel junction layer storing predefined information by causing a magnetization direction to be up or down, a spin-current transfer layer transferring spin current to the magnetic tunnel junction layer, a spin-current generation layer generating the spin current, and a thermal electron injection layer injecting thermal electrons into the spin-current generation layer, and the magnetization direction may be changed due to spin transfer torque generated in the magnetic tunnel junction layer, whereby it is possible to reduce current density consumed for switching the magnetization direction of the free magnetic sub-layer in the magnetic tunnel junction layer.

Claim (Index 1):
A magnetic RAM including a memory cell, the memory cell comprising:\n a metal layer provided with a first electrode terminal for receiving a first voltage pulse; a magnetic tunnel junction layer disposed in contact with a lower surface of the metal layer to store predefined information by causing a magnetization direction of at least a part thereof to be up or down; a spin-current transfer layer disposed in contact with a lower surface of the magnetic tunnel junction layer and provided with a second electrode terminal for receiving a second voltage pulse to transfer spin current to the magnetic tunnel junction layer; a spin-current generation layer disposed in contact with a lower surface of the spin-current transfer layer to generate the spin current to be transferred to the magnetic tunnel junction layer through the spin-current transfer layer; and a thermal electron injection layer disposed in contact with a lower surface of the spin-current generation layer and provided with a third electrode terminal for receiving a third voltage pulse to inject thermal electrons into the spin-current generation layer so that the spin current is generated in the spin-current generation layer, wherein the magnetization direction of at least a part of the magnetic tunnel junction layer is changed due to a spin transfer torque generated in at least the part of the magnetic tunnel junction layer by the spin current.
