摘要： One main electrode of a TFT is connected with one terminal of a two-terminal type nonvolatile memory element, a gate electrode of the TFT is connected with a word line, and the other main electrode thereof is connected with a bit line. The other terminal of the memory element is connected with a base line. A fixed resistor is connected between a connecting point between the other main electrode of the TFT and the bit line and an input terminal of the bit line. In information writing for changing the memory element whose initial state is a low impedance state to a high impedance state, voltages having polarities reverse relative to a reference voltage are applied to the input terminal of the bit line and an input terminal of the base line, respectively, so that a high voltage necessary to change the state is applied between both the terminals of the memory element.

摘要： An unauthorized access prevention method is provided for an integrated circuit including one or plural resistor elements capable of selecting between a high impedance state and a low impedance state irreversibly in an interface portion within the integrated circuit or a peripheral circuit portion. When a signal inconsistent with verification information and standard that are preset in the integrated circuit is received at least once, the impedance state of the resistor element is changed from an initial state to stop a part or all of accesses to the integrated circuit irreversibly. The unauthorized access prevention method is thus implemented by a simple structure manufactured with ease and at low cost.

Alternatively, a magnetic random access memory includes a plurality of first wirings for applying a magnetic field in the direction of the easy magnetization axis of a magnetic layer, and a plurality of second wirings for applying a magnetic field in a direction inclined from the direction of the easy magnetization axis of the magnetic layer, wherein a current is passed through one of the second wirings to apply a magnetic field to all memory elements arranged in a same row or column of the rows or columns of a plurality of the memory cells arranged in parallel to the second wirings, and currents are passed through the plurality of first wirings in directions according to the information to be recorded in the respective memory elements synchronously with the current pulse passed through the second wiring to apply a magnetic field to each of the magnetoresistive elements, thereby recording information on the plurality of memory elements arranged in the same row or column.
