Abstract

An electronic device may include a first electrode, a first piezoelectric layer electrically coupled to the first electrode, a first magnetostrictive layer above the first piezoelectric layer, a first tunnel barrier layer above the first magnetostrictive layer, and a ferromagnetic layer above the first ferroelectric layer. The electronic device may further include a second electrode electrically coupled to the ferromagnetic layer a second tunnel barrier layer above the ferromagnetic layer, a second magnetostrictive layer above the second tunnel barrier layer, a second piezoelectric layer above the second magnetostrictive layer, and a third electrode electrically coupled to the second piezoelectric layer. The first piezoelectric layer may be strained responsive to voltage applied across the first and second electrodes, and the second piezoelectric layer may be strained responsive to voltage applied across the second and third electrodes.
