  • Patent number: 8395953
    Abstract: The bit-line sense amplifier includes a driving-voltage control circuit and an amplifier. The driving-voltage control circuit generates a first test driving voltage having a voltage level of a pre-charge voltage, a second test driving voltage having a voltage level of a pre-charge voltage added by a voltage difference between a bit-line and a complementary bit-line, and a third test driving voltage having a voltage level of a pre-charge voltage subtracted by the voltage difference in a test mode. The amplifier senses and amplifies a voltage difference between the bit-line and the complementary bit-line.

  • Patent number: 8379477
    Abstract: Provided is a semiconductor memory device including a sub-word-line driving circuit capable of reducing an amount of leakage current due to coupling. The semiconductor memory device includes a word-line enable signal generating circuit and a sub-word-line driving circuit. The sub-word-line driving circuit provides a pull-down current path between a selected word line and ground for a pulse type period of time in a precharge mode following an active mode for the selected word line, generates a word line driving signal on the basis of a main word line driving signal, a first sub-word-line control signal, and a second sub-word-line control signal, and provides the word line driving signal to a memory cell array. The semiconductor memory device may reduce an amount of leakage current flowing to a ground through the sub-word-line driving circuit.

  • Patent number: 8027675
    Abstract: An apparatus and method for controlling registration of a mobile identification number (MIN) of a mobile communication terminal. A memory stores a table in which MIN groups uniquely assigned to common carriers are stored, and a MIN of a mobile communication terminal. An input device inputs a MIN to be stored in the memory. If the MIN stored in the memory is a default MIN, a controller replaces the MIN stored in the memory with the MIN input from the input device. If the MIN stored in the memory is not the default MIN and the input MIN belongs to a MIN group assigned to a common carrier corresponding to the stored MIN, the controller replaces the stored MIN with the input MIN.
