    Abstract: PROBLEM TO BE SOLVED: To provide a magnetic random access memory element which can store multi-bits.
    SOLUTION: The magnetic random access memory element is made from a first magnetic tunnel junction and a second magnetic tunnel junction. These magnetic tunnel junctions are connected to each other in a series resistive circuit. The connected first and second magnetic tunnel junctions are connected to a bit line through an access transistor. A write bit line and a write data line are associated with each of the first and second magnetic tunnel junctions. By application of appropriate currents to these lines , the magnetic vector orientation with each of the first and second magnetic tunnel junctions can be controlled so as to store within the element in any one of at least three logic states.

    Abstract: PROBLEM TO BE SOLVED: To provide an advanced IP address lookup technology. SOLUTION: Internet Protocol address prefixes are hashed into hash tables allocated memory blocks on demand after collisions occur for both a first hash and a single rehash. The number of memory blocks allocated to each hash table is limited, with additional prefixes, handled by an overflow content addressable memory. Each hash table contains only prefixes of a particular length, different hash tables contain prefixes of different lengths. Only subset of possible prefix lengths are accommodated by the hash tables, a remainder of prefixes is handled by the content addressable memory or a similar alternate address lookup facility.

    Abstract: PROBLEM TO BE SOLVED: To provide technique for performing error correction and error detection on a wide data word in a memory system and other systems including a memory.
    SOLUTION: A parity generation circuit includes a plurality of bit generation circuits. Each of the bit generation circuits operates to receive each data bit and each hard latch signal, and generate a parity signal indicating the parity of the corresponding data bit when the hard latch signal is inactive. Each of the bit generation circuits drives the parity signal to a setting value when the hard latch signal is active. An output circuit is coupled with a bit generation circuit to receive the parity signal, and operates to generate an output parity signal in response to the parity signal from the bit generation circuit.

    Abstract: PROBLEM TO BE SOLVED: To provide an integrated and released beam layer structure manufactured in a trench and its manufacturing method.
    SOLUTION: The beam layer structure has a semiconductor substrate 20, the trench 18, a first electrical conducting layer 24, and the beam 28. The trench is extended inside the semiconductor substrate and has a wall. The first electrical conducting layer is positioned on the wall of the trench in the selected position. The beam is positioned on the trench, and the first part of it is connected to the semiconductor substrate, and a second part of it is movable. The second part of the beam is separated from the wall of the trench by the selected distance. Therefore, the second part of the beam is freely movable inside the plane vertical or parallel to the surface of the substrate, and can be deflected, that is, deformed relative to the trench so as to electrically contact in response to a predetermined acceleration force applied to the beam structure or the change of a predetermined temperature.

    Abstract: PROBLEM TO BE SOLVED: To provide a technique to determine the direction of rotation of a sensorless motor operating in the state of freewheel, by comparing signals induced in a motor winding. SOLUTION: A device and method for determining the freewheel rotation of an electric motor is provided comprises a step to measure first and second signals from first and second windings of an unenergized motor, respectively, and a step to determine whether or not an energized motor is rotating from the first and second signals. The method can also determine the direction of rotation from the first and second signals when the unenergized motor is rotating. Further the method can measure a third signal from a third winding of the unenergized motor, and when determining whether or not the motor is rotating the method can determine that the motor is not rotating if the first, second and third signals are equal. Each of the first and second signals can have a back-voltage. COPYRIGHT: (C)2005,JPO&NCIPI
