    摘要: Provided is a method for reading data from a variable resistance nonvolatile storage element, where the operation for reading data is less susceptible to a fluctuation phenomenon of resistance values in reading the data. The method includes: detecting a current value Iread that flows through the nonvolatile storage element that can be in a low resistance state RL and a high resistance state RH, with application of a fixed voltage; and determining that (i) the nonvolatile storage element is in a high resistance state when the current value Iread detected in the detecting is smaller than a current reference level Iref, and (ii) the nonvolatile storage element is in a low resistance state when the current value Iread detected in the detecting is larger than the reference level Iref, the current reference level Iref being defined by (IRL+IRH)/2

    摘要: Each of memory cells (MC) includes one transistor and one resistance variable element. The transistor includes a first main terminal, a second main terminal and a control terminal. The resistance variable element includes a first electrode, a second electrode and a resistance variable layer provided between the first electrode and the second electrode. A first main terminal of one of two adjacent memory cells is connected to a second main terminal of the other memory cell, to form a series path (SP) sequentially connecting main terminals of the plurality of memory cells in series. Each of the memory cells is configured such that the control terminal is a part of a first wire (WL) associated with the memory cell or is connected to the first wire associated with the memory cell, the second electrode is a part of a second wire (SL) associated with the memory cell or is connected to the second wire associated with the memory cell; and the first electrode is a part of a series path (SP) associated with the memory cell or is connected to the series path associated with the memory cell.
