    摘要: A CAM unit has a memory array for storing storage data, and a RAM unit has a memory array for storing the same storage data and check bits added thereto for determining whether the storage data in its memory array has an error. An error correction circuit uses the check bits to correct any error of data read from the memory array of the RAM unit and rewrite the error-corrected data to the memory arrays. Even if a soft error occurs in the storage data, the check bits can be used to correct the error in the data and rewrite the error-corrected data. Thus, a matching comparison can be performed on the storage data with high reliability.

    摘要: A CAM (Content Addressable Memory) cell includes first and second data storage portions storing data, horizontal port write gates for storing data applied through a match line pair in the data storage portions in a data write through a horizontal port, and search/read gates for driving the match lines of the match line pair in accordance with the data stored in the data storage portions in a search operation and in a data read through the horizontal port. The match lines are used as horizontal bit line pair, or signal lines for accessing the horizontal port. As the first and second data storage portions are used, it becomes possible to store ternary data, and accordingly, a write mask function of inhibiting a data write at a destination of data transfer is realized. Further, as the CAM cell is used, an arithmetic/logic operation following a search process can be executed selectively, and high speed data writing/reading becomes possible.

    摘要: An orthogonal memory for transforming arrangements of system bus data and processing data is placed between a system bus interface and a memory cell mat storing the processing data. The orthogonal memory includes two-port memory cells, and changes data train transferred in a bit parallel and word serial fashion into a data train of word parallel and bit serial data. Data transfer efficiency in a signal processing device performing parallel operational processing can be increased without impairing parallelism of the processing.

    摘要: In a parallel operational processing device having an operational processing unit arranged between memory blocks each having a plurality of memory cells arranged in rows and columns, the respective columns of each memory block are alternately connected to the operational processing units on the opposite sides of the memory block. By selecting one word line in one memory block, data can be transferred to two operational processing units. The number of the word lines selected per one operational processing unit is reduced, and power consumption is reduced. The bit operation units and sense amplifiers/write drivers of the operational processing units have arrangement pitch conditions mitigated and are reduced in number, and an isolation region between the memory blocks is not required and the layout area is reduced. Thus, the parallel operational processing device with a layout area and the power consumption reduced, can achieve a fast operation.

    摘要: A memory cell mat is divided into a plurality of entries, and an arithmetic logic unit is arranged corresponding to each entry. Between the entries and the corresponding arithmetic logic units, arithmetic/logic operation is executed in bit-serial and entry-parallel manner. Where parallel operation is not very effective, data is transferred in entry-serial and bit-parallel manner to a group of processors provided at a lower portion of the memory mat. In this manner, a large amount of data can be processed at high speed regardless of the contents of operation or data bit width.

    摘要: A disposable microbe-collecting carrier cartridge and a carrier treating apparatus which efficiently convert microbes collected on a carrier into a solution and prevent variations in the amount of retrieval of microbes upon concentration on a filter are provided. A cartridge formed of an upper lid having a plurality of through holes, a container in an inverted-cone shape having both of a liquid storage sink unit having a filter at the bottom and an air suction path, and a support base for setting up a thermoplastic carrier, such as gelatin, and a carrier treating apparatus formed of a dispensing nozzle for liquid supply, a liquid supply mechanism, a liquid heating mechanism, and a suction pump for filtration are prepared. Warm water is supplied onto the filter set up on a bottom surface of the inverted-cone-shaped container and is stored in the liquid storage sink, thereby causing the carrier to make contact with the warm water. The contact with the warm water causes the carrier to be solated, and mixed and diluted with the warm water. Then, the suction pump of the filtration device is activated for suction and filtration of the mixed liquid through the filter. By using the filter having a shape not allowing microbes to pass through and having a gap, only microbes are captured on the filter after suction and filtration. Polymers and dust to be a background upon an ATP measurement pass through the filter by filtration to be cleanly eliminated.

    摘要: A chemical reaction device is provided for a chemical reaction between molecules immobilized on a solid phase and molecules in a solution, and a chemical analysis device is also provided to capture molecules in the solution by molecules immobilized on the solid phase through a chemical reaction and subsequent measurement of the captured molecules. Reaction efficiency as well as sample throughput are thereby improved. The chemical reaction device and the chemical analysis device use a channel of a microfluidic device for a reaction vessel, and at least a particular molecule is immobilized on an interior surface and a fixed structure or a non-fixed obstacle against a flow is provided in the channel. In a typical reaction vessel having an enzyme immobilized on an interior surface of a capillary and glass beads functioning as an obstacle for the flow filled in the channel of the capillary, a reaction solution can move either in one direction or back and forth in two directions to thereby undergo a reaction with the enzyme immobilized on the interior surface. The flow of the reaction solution is not a laminar flow so that a reaction between the particular molecule immobilized and the reaction solution proceeds at high efficiency.
