Claim:
1. A memory device, comprising: a magnetic storage element; and an access transistor, coupled to the magnetic storage element, having a first gate and a second gate, wherein the first gate and the second gate are configured to be isolated electrically from each other, and wherein the first gate is configured to activate the access transistor and the second gate is configured to adjust a threshold voltage value of the access transistor; a word line coupled to the access transistor; and first and second fin field effect transistor (FinFET) based sources, wherein the first FinFET based source is configured to be at a greater potential than the second FinFET based source to orient a magnetization direction of the magnetic storage element in a first direction corresponding to a logical one or at a lesser potential than the second FinFET based source to orient the magnetization direction of the magnetic storage element in a second direction corresponding to a logical zero, and wherein the access transistor is configured to be activated, in response to controlling the word line, to provide a first current from the first FinFET based source to the second FinFET based source to orient the magnetization direction of the magnetic storage element in the first direction or to provide a second current from the second FinFET based source to the first FinFET based source to orient the magnetization direction of the magnetic storage element in the second direction.
