Abstract

An approach to provide a funnel-shaped spin-transfer torque (STT) magnetoresistive random-access memory (MRAM) device with a dual magnetic tunnel junction. The approach includes providing a metal pillar on a connection to a semiconductor device. The approach includes providing a first reference layer on the metal pillar and on a portion of a first interlayer dielectric adjacent to the metal pillar. The approach includes providing a first tunnel barrier on the first reference layer and a free layer on the first tunnel barrier layer. The approach includes providing a second tunnel barrier on the free layer and a second reference layer on the second tunnel barrier of the semiconductor structure of the funnel-shaped spin-transfer torque MRAM device.
