    Abstract: A data transceiver device for near field communication is provided which includes a matching and filtering circuit connected between an antenna and a transceiver and configured to conduct filtering and impedance matching for a reception signal and a transmission signal. The matching and filtering circuit includes a variable attenuator of which the impedance varies with a frequency so that an attenuation ratio of the reception data is smaller than that of the reception carrier signal.

    Abstract: Aggressor memory cells connected to one or more aggressor wordlines are grouped into aggressor cell groups by performing a read operation with respect to the aggressor wordlines based on one or more grouping read voltages, where the aggressor wordlines are adjacent to a selected wordline corresponding to a read address among wordlines of a memory block. Selected memory cells connected to the selected wordline are grouped into a selected cell groups respectively corresponding to the aggressor cell groups. Group read conditions respectively corresponding to the selected cell groups are determined and group read operations are performed with respect to the plurality of selected cell groups based on the group read conditions. The read errors are reduced by grouping the selected memory cells into the selected cell groups according to the change of operation environments.

    Abstract: A near field communication device includes an antenna, a matching circuit connected to the antenna, a clock extraction block that extracts a clock from a signal received by the antenna and outputs the extracted clock, a frequency compensation block that compensates for a frequency of the extracted clock and outputs a compensated clock, and a modulation and amplification block that performs modulation and amplification by using the compensated clock and outputs a transmit signal to the matching circuit. A first extracted clock has a first frequency that is extracted when the transmit signal is not output and a second extracted clock has a second frequency that is extracted when the transmit signal is output, the frequency compensation block compensates for the second frequency of the second extracted clock based on a difference between the first frequency of the first extracted clock and the second frequency of the second extracted clock.

    Abstract: A bi-directional voltage converter of a smart card includes switching elements connected between an input node and an output node and a start-up transistors whose channel width over channel length is smaller than a channel width over channel length of the switching element. The bi-directional voltage converter stores a driving voltage applied to an output node in a storage capacitor during a booting operation and provides the voltage stored in the storage capacitor to an input node. The bi-directional voltage converter may boost another driving voltage at the input node step-wisely and may perform bi-directional voltage converting with reduced occupied area and high efficiency.
