Abstract: Disclosed is an electric field-controlled magnetoresistive random-access memory (MRAM) including memory cells. The memory cell has a heterogenous double tunnel junction structure including a first tunnel junction and a second tunnel junction. The first tunnel junction includes a magnetic tunnel junction layer having a magnetization direction that changes according to spin transfer torque when an external voltage is applied, and the second tunnel junction includes an electric-field control layer that controls an electric field applied to the magnetic tunnel junction layer to induce a change in magnetic anisotropy within the magnetic tunnel junction layer. The heterogeneous tunnel junction structure combines electric field-controlled magnetic anisotropy and spin transfer torque to enable low power driving of memory cells, thereby enabling a high energy-efficient electric field-controlled MRAM.
