    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.

  • Patent number: 7859235
    Abstract: A first output transistor forms a first current path between an input and an output terminal and has a first control terminal applied with a first control signal. A second output transistor forms a second current path between the output and a ground terminal and has a second control terminal applied with a second control signal. A first comparator outputs the first control signal to decrease an ON-resistance of the first transistor when an output voltage from the output terminal is a predetermined value or less. A second comparator outputs the second control signal to render the second transistor conductive to decrease the output voltage when the output voltage is a predetermined value or more. An acceleration circuit accelerates charging of the first control terminal of the first transistor to a predetermined potential. The inhibition circuit inhibits the acceleration circuit operation according to a change of the second control signal.

  • Publication number: 20100222095
    Abstract: An input device capable of avoiding simple input of the correct password and a portable telephone device are provided. A contact sensor (56) enabling input of a line by moving a finger of the user on an area where numeric keys (48) of a portable telephone (10) are arranged is provided in the area. When password information for canceling key-lock is registered, the user moves a finger of the user on the contact sensor (56) to input a linear shape. The data on the key with which the user first comes to contact when the user tries to input the line and the data on the key from which the user separates the user's finger last are registered for each place, thus completing the registration of the password. When the user wants to cancel the key-lock, the user operates the contact sensor similarly to the registered content. Then the key-lock is canceled.
