Abstract: A method and circuit for sampling and writing data in a double data rate (DDR) memory device, capable of securing sufficient setup and hold margins regardless of the operation frequency. Transferring first and second sampled input data to a first path using a first path control signal. Transferring third and fourth sampled input data to a second path using a second path control signal. The first and second path control signals are one half-cycle out of phase. First to fourth data are successively sampled in synchronization with a rising or falling edge of a first external clock signal; The sampled first data is linked onto a first path and the sampled second data is linked onto a second path in response to the first path control signal (generated in synchronization with a falling edge of the external clock signal); the first data on the first path and the second data on the second path are written to the memory cells in response to a write clock signal.

Abstract: A planar small antenna and a small strip radiator are provided which have increased bandwidth. The small strip radiator has a main strip pattern and a plurality of convoluted strip patterns terminating the main strip pattern at each end. The plurality of convoluted strip patterns are arranged in mirror-symmetrical arrangement with reference to the longitudinal axis of the main strip such that one pair of convoluted strip patterns is convoluted clockwise while another pair is convoluted counterclockwise. As a result, an electrically small antenna radiator requires less metal or conductive material than conventional radiators, and also can operate without adversely affecting the radiation characteristics of the antenna.
