摘要： A nonvolatile semiconductor memory device according to an embodiment herein includes a memory cell array. The memory cell array includes memory cells each provided between a first line and a second line and each including a variable resistor. A control circuit applies through the first and second lines a voltage necessary for a forming operation of the memory cell. A current limiting circuit limits a value of a current flowing across the memory cell during the forming operation to a certain limit value. The control circuit repeats an operation of applying the voltage by setting the limit value to a certain value and an operation of changing the limit value from the certain value, until forming of the memory cell is achieved.

摘要： An ID tag has a stable internal supply voltage and extends the range of communication with the reader/writer during back scattering communication. An ASK-modulated signal pre-boost circuit to which antenna terminals are coupled is coupled in parallel with a rectifying circuit. In the ASK-modulated signal pre-boost circuit, a switch for back scattering, working as a modulator element, is provided. During back scattering communication, when a back scattering signal “1” is transmitted, only the current flowing in the signal receiving path of the modulation/demodulation unit is wasted by turning the switch for back scattering on. Additional current loss other than the loss for impedance matching can be prevented.

摘要： A memory cell arranged between first and second wirings includes a variable-resistor element. A controller controls a voltage applied between the first and second wirings. The controller performs a first operation that applies a first voltage between the first and second wirings to switch the variable-resistor element from a first state with a resistance value not less than a first resistance value, to a second state with a resistance value not more than a second resistance value smaller than the first resistance value. The second operation applies a second voltage smaller than the first voltage between the first and second wirings to switch the variable-resistor element from the second state to the first state. In the first operation, a verify voltage is applied between the first and second wirings. Based on the obtained signal, a third voltage smaller than the first voltage is applied between the first and second wirings.
