    摘要: In a magnetic random access memory (MRAM), and a method of reading data from the same, the MRAM includes a memory cell having one transistor and one magnetic tunneling junction (MTJ) layer, and a reference cell that is operable for use as a basis when reading data stored in the memory cell, wherein the reference cell includes first and second MTJ layers provided in parallel to each other, and first and second transistors provided in parallel to each other, the first and second transistors being respectively connected in series to the first and second MTJ layers. Alternatively, one transistor having a driving capability corresponding to twice a driving capability of the transistor of the memory cell may be substituted for the first and second transistors of the reference cell.
