Abstract (in Japanese) (See Japanese page) 
(in English) A device-variation-tolerant spin-transfer-torque magnetic random access memory (STT-MRAM) cell array with a high-signal-margin reference generator circuit was developed to achieve high-density 1T1MTJ STT-MRAMs. Fluctuations in the memory cell characteristics were first measured using a 1-kbit STT-MRAM test chip. Based on these measurements, a reference generator and an STT-MRAM cell array architecture were proposed. This cell array was evaluated in terms of the signal margin for read operation by means of Monte-Carlo SPICE circuit simulations. The proposed design enables a 50% improvement in the signal margin compared with the conventional cell array circuit.
