  • Patent number: 9502314
    Abstract: Disclosed herein is a method for manufacturing a tested apparatus that includes forming a stacked structure that includes a plurality of first semiconductor chips stacked over a semiconductor wafer. The semiconductor wafer comprises a plurality of second semiconductor chips that are arranged in matrix of a plurality of rows and columns. Each of the first semiconductor chips is stacked over and electrically connected to a different one of the second semiconductor chips. The method further includes contacting a probe card to at least one of the first semiconductor chips to perform a first test operation on a corresponding one of the second semiconductor chips with an intervention of the at least one of the first semiconductor chips so that a plurality of tested apparatus each comprising a pair of first and second semiconductor chips stacked with each other is derived.

  • Patent number: 9142469
    Abstract: A device comprises a semiconductor chip including an edge elongated in a first direction. A plurality of first pads is formed on the semiconductor chip. The first pads are substantially equal in length in the first direction to each other. A second pad is formed on the semiconductor chip. The second pad is greater in length in the first direction than the first pads. The first pads and the second pad are arranged in a line elongated in the second direction, that is substantially perpendicular to the first direction, without an intervention of any one of the first pads between the second pad and the edge.

  • Patent number: 5923580
    Abstract: For reducing the area for read/write bus lines to a half and shortening the length of the read/write bus lines so as to speed up the operation, the locating positions of input/output circuits for the corresponding bits, of memory blocks MB1 and MB3a located to oppose to each other and to interpose therebetween an active circuit area ACA and of memory blocks MB2a and MB4 located to oppose to each other and to interpose therebetween the active circuit area ACA, are made different from each other. Read/write bus lines RWB1 to RWB4 of the same length are formed and located to interconnect between the inputs/outputs for the corresponding bits, of the opposing memory blocks, by traversing an empty region between circuit blocks CB in the active circuit area ACA, and in such a manner that each two read/write bus lines extend between the memory blocks MB1 and MB2a and between the memory blocks MB3a and MB4.

  • Patent number: 5165016
    Abstract: An image data output apparatus including a page-link memory, for storing data pertaining to the relationship between the logical address and the physical address, of the image data, and an address-translation unit for translating logical page addresses into physical page addresses. The apparatus can perform quick, accurate accessing of the image data, in a direction across the adjacent pages. The frame memory can undergo reallocation, so that the least possible data is transferred upon generation of the boundary condition of a frame memory.
