Abstract: The present invention provides a method for eliminating crosstalk (coupling noise) in a metal programmable read only memory. The metal programmable read only memory comprises a plurality of bit lines, a plurality of word lines, a plurality of precharge transistors, and a plurality of clamp transistors. When one of the bit lines is selected, bit lines adjacent to the selected bit line are fixed to a voltage value (VDD, GND or other voltages) by the clamp transistors. The clamping method can not cause voltage drops to the adjacent bit lines, and the crosstalk on the selected bit line can be eliminated simultaneously, so that the problem of read failures caused by the crosstalk in the high-speed metal programmable read only memory can be solved, and a higher speed can be reached.

Abstract: The present invention provides a power gating structure having data retention and intermediate modes and able to operate under multiple modes. A conventional power gating structure has only turn-on and turn-off functions, and is used to suppress a leakage current problem which has become more and more serious in advance manufacture processes, under a turn-off mode. However, in a memory circuit, such as latch, register and SRAM, when the power gate is turned off, a new power gating structure is required for data retention. The power gating structure of the present invention can be set into one of 4 different operational modes: a data retention mode for maintaining the static noise margin of the memory, an intermediate mode for reducing the interference on ground and power levels, an active mode used when the circuit operates in normal condition, and a standby mode used when the circuit does not operate.

Abstract: A bamboo mat board element with a double-layered construction, a constant dimension, each of the elements is formed with a projecting tenon at each of two adjacent sides, respectively, and a concave mortise at each of the other two adjacent sides, respectively, for inter-tenoning the elements of the mat board, in which a surface layer of the mat board is obtained by matting a plurality of mat board stuffs having different orientations, shapes, and sizes, while each of the mat board stuffs is obtained by matting a plurality of lumbers having a parallel orientation, respectively, to form a plurality of patterns having parallel stripes by specially matting at the longitudinal section thickness of the lumbers. A method for producing the bamboo mat board at least comprises steps as follows: cutting step, boiling for blanching step, drying step, rough shaving, bottom layer pre-forming step, adhesive applying and pressing step, pattern selecting step, matting step, and refined shaving, etc.

Abstract: There is disclosed a fastener for clips to be applied to jewelry and costume jewelry products and to clothing accessories, bags and the like. The fastener utilizes a mechanical device actuated through the action of magnets. According to one arrangement, the mobile components of the clip, shaped substantially in the form of small pins that carry out the mechanical fastening, consist of magnets, for which, in each pair of said permanent magnets, there is mutual attraction and therefore closing of the fastening device when they are arranged with the poles opposite, i.e. when one is arranged in such a way that its positive pole faces towards the negative pole of the other.
