Technologies for realizing high density MRAM were developed. First, new circuitry to lower the resistance of programming wires was developed. Second, both MTJ plane shape and cross-sectional structure were optimized to lower the programming current.

In order to realize a sub-Giga bit scale NVRAM, the novel MRAM based on the spin-transfer-torque (STT) switching has been intensively investigated due to its excellent scalability compared with a conventional magnetic field induce switching MRAM [1].

A comprehensive statistical model of the switching probability was proposed for a 1 Gb spin transfer torque magneto resistive random access memory (STT-MRAM). Since the switching current varies with every write cycle owing to the thermal instability,

A spin transfer torque magnetoresistive random access memory (STT-MRAM) is the most promising candidate for a non-volatile random access memory, because of its scalability, high-speed operation, and unlimited read/write endurance. An ion beam etching

In this paper, the switching current distribution by spin transfer torque is investigated for CoFeB∕MgO∕CoFeB magnetic tunnel junctions (MTJs). The distribution of the spin transfer switching current for a MTJ with junction size of 85×110nm2 is
