Abstract:
1. A spin-torque transfer memory random access memory (STTMRAM) cell comprising: a selected magnetic tunnel junction (MTJ) identified to be programmed by switching the state thereof upon application of a switching current sufficient to switch the state of the selected MTJ, the selected MTJ having a first end and a second end; a first transistor having a first port, a second port and a gate, the first port of the first transistor coupled to the selected MTJ at the first end of the selected MTJ; a first neighboring MTJ having a first end and a second end, the first end of the first neighboring MTJ coupled to the selected MTJ through the second port of the first transistor; a second transistor having a first port, a second port, and a gate, the first port of the second transistor coupled to the selected MTJ at the first end of the selected MTJ; a second neighboring MTJ having a first end and a second end, the first end of the second neighboring MTJ coupled to the selected MTJ through the second port of the second transistor; a first bit/source line coupled to the second end of the selected MTJ; and a second bit/source line coupled to the second end of the first neighboring MTJ and the second end of the second neighboring MTJ.
