  • Publication number: 20150143097
    Abstract: An information processing apparatus that can flexibly change an amount of data to be saved. A determining unit determines, at a time when the information processing apparatus is started up, whether termination processing has abnormally ended last-time or not. A detecting unit detects an instruction indicating processing that should be performed at the time of the start-up when the determining unit determines that the termination processing has abnormally ended last-time. A saving unit saves, under the instruction detected by the detecting unit, data stored in a save area determined by the instruction from among storage areas of a nonvolatile main storage device, to a save destination determined by the instruction.

  • Patent number: 8901990
    Abstract: In the device, a pair of transistors includes first and second transistors connected in parallel between a power-supply-line and a power-supply or between a ground-line and a ground-potential. A third transistor is connected between the power-supply-line and the power-supply or between the ground-line and the ground-potential. First to third nodes are gate nodes of the first to third transistors. A first buffer outputs a first control-signal for controlling the first transistor. A second buffer is connected between the first node and the second and third nodes to receive the first control-signal and transmit a second control-signal for controlling the second and third transistors to the second and third nodes in parallel. When power-supplying starts, the second control signal drives the second and third transistors to the conductive-state after the first control-signal controls the first transistor to be driven in an intermediate-state between the conductive-state and a shutoff-state.

  • Patent number: 8856614
    Abstract: According to one embodiment, a semiconductor memory device includes first to fifth units. The first unit compares first data being write target data before write in a memory, with second data written in the memory and then read out. The second unit stores the first data if a data comparison result indicates mismatch. The third unit stores a write address corresponding to the write target data if the data comparison result indicates mismatch. The fourth unit compares a read address corresponding to read target data with an address stored in the third unit. The fifth unit selects data read out from the memory in accordance with the read address as the read target data if a address comparison result indicates mismatch, and selects data read out from the second unit as the read target data if the address comparison result indicates match.

  • Publication number: 20140245434
    Abstract: A contact sensor capable of inputting a character by tracing a character with user's finger is arranged in a region of a ten-key unit of a mobile telephone. When registering a password to release a key lock, a user traces a shape of a line, a character, a number, or other symbol on the contact sensor with his/her finger so that the shape is inputted and stored in a memory, thereby completing registration of a password. When releasing the key lock, the user traces the registered shape on the contact sensor with his/her finger so that the key lock is released. The input is easy. Even if the password input operation is observed by a third person, the password will not be easily known to the third person.
