Abstract

A method and system for providing a magnetic memory is described. The method and system include providing a plurality of magnetic storage cells. Each of the plurality of magnetic storage cells includes a magnetic element and a selection transistor. The magnetic element may be programmed using spin transfer induced switching by a write current driven through the magnetic element. The selection transistor includes a source and a drain. The plurality of magnetic storage cells are grouped in pairs. The source of the selection transistor for one magnetic storage cell of a pair shares the source with the selection transistor for another magnetic storage cell of the pair.
