Abstract

A magnetic memory includes memory array tiles (MATs), intermediate circuitry, global bit lines and global circuitry. The magnetic memory and a method for programming the magnetic memory are provided. Each MAT includes bit lines, word lines, and magnetic storage cells having magnetic junction(s), selection device(s) and at least part of a spin-orbit interaction (SO) active layer adjacent to the magnetic junction(s). The SO active layer exerts a SO torque on the magnetic junction(s) due to a preconditioning current passing through the SO active layer. The magnetic junction(s) are programmable using write current(s) driven through the magnetic junction(s) and the preconditioning current. The bit and word lines correspond to the magnetic storage cells. The intermediate circuitry controls read and write operations within the MATs. Each global bit line corresponds to a portion of the MATs. The global circuitry selects and drives portions of the global bit lines for read operations and write operations.
