Abstract: A memory device includes a plurality of arrays coupled in parallel with each other. A first array of the plurality of arrays includes a first switch and a plurality of first memory cells that are arranged in a first column, a second switch and a plurality of second memory cells that are arranged in a second column, and at least one data line coupled to the plurality of first memory cells and the plurality of second memory cells. The second switch is configured to output a data signal from the at least one data line to a sense amplifier.

Abstract: One aspect of this description relates to a memory array. In some embodiments, the memory array includes a first memory cell coupled between a first local select line and a first local bit line, a second memory cell coupled between a second local select line and a second local bit line, a first switch coupled to a global bit line, a second switch coupled between the first local bit line and the first switch, and a third switch coupled between the second local select line and the first switch.

Abstract: A memory circuit includes a first memory cell on a first layer, a second memory cell on a second layer different from the first layer, a first select transistor on a third layer different from the first layer and the second layer, and a first bit line extending in a first direction, and being coupled to the first memory cell and the second memory cell. The memory circuit further includes a first source line extending in the first direction, being coupled to the first memory cell, the second memory cell and the first select transistor, and being separated from the first bit line in a second direction different from the first direction. memory circuit includes a second source line extending in the first direction, and being coupled to the first select transistor.

Abstract: A method is provided for modifying a radioactive carbon nanotube (CNT) carrier. Magnetic molecules are used. The modified CNT is highly specified to disease. Surface of the CNT has functional grafts for catching antigen/antibody. Antigen/antibody thus caught on the surface is increased in number. Thus, the present invention improves sensitivity and accuracy of disease detection and greatly saves cost. The present invention can be applied for sample purification or massive disease detection.

Abstract: A detection method for cancer is provided. Magnetic carbon beads are used. The carbon beads are highly specified to a cancer. Surface area of grafted antigen are broadened by grafting functional molecules. Number of antigen is increased on the surface. Thus, the present invention improves sensitivity and accuracy of disease detection and greatly saves cost. The present invention can be applied for sample purification or massive disease detection.

Abstract: A method of preparing magnetic bead type nasopharyngeal enzyme immunoassay reagents by polymerase chain reaction according to this invention offers in-vitro diagnostic reagents by means of utilizing nanotechnology. This method uses magnetic beads to coat EBV nuclear antigen (Epstein-Barr virus nuclear antigen, EBNA1) or early antigen (Early Antigen, EA). The use of polymerase chain reaction (polymerase Chain Reaction PCR) is for amplified detection. It is found that positive controls of different concentrations, after amplified by PCR, change in their brightness and concentration. That reveals the EBV antigens on the magnetic beads can specifically detect IgA antigens in the serum.
