This invention relates to an MRAM array architecture which incorporates certain advantages from both cross-point and 1T-1MTJ architectures during reading operations. The fast read-time and higher signal to noise ratio of the 1T-1MTJ architecture and the higher packing density of the cross-point architecture...http://www.google.com/patents/US20040057276?utm_source=gb-gplus-sharePatent US20040057276 - Stacked columnar 1T-nMTJ MRAM structure and its method of formation and operation
