    摘要: In LSI circuit devices having a plurality of subchips packaged therein and having specific functions, capacitance cutting buffer circuits are employed in conjunction with respective terminals of the subchips, and a driver is disposed at respective points where relatively long wiring lines are respectively sub-divided into a corresponding plurality of lines. As a result, signal transmission delay can be significantly reduced. The terminals of the subchips are also provided with a probing pad to test the operations of the subchips independently of one another. The subchips employ circuit blocks which are to operate simultaneously and in conjunction with the wirings of the subchips, power supply lines are disposed correspondingly to the distributively arranged circuit blocks. Bus lines also controllably transmit addresses as well as data signals in a time sharing manner. Furthermore, each of the subchips has a fault test circuit. The subchips which have a DC fault is electrically isolated thereby allowing the remainder of the subchip to be usable. In the fault relieving technique employed, a combination of memory locations wherein no fault exists is selected for use, thereby allowing the construction of an LSI even with subchips which correspond to faulty bit addresses. The fault relieving technique employed uses an address converting circuit for faulty addresses, this operation being performed automatically within the chip system.

    摘要: A plurality of unit integrated circuits mounted on a large-scale integrated circuit device, for example, a wafer scale memory, are each provided with a bypass circuit which selectively shorts input and output nodes in the corresponding unit integrated circuit. By selectively bringing the bypass circuit into a transfer state, it is possible to effectively couple together all unit integrated circuits which are judged to be normal among a plurality of unit integrated circuits disposed along one row, for example. Improved redundancy arrangements are also provided, including first and second redundant elements for the unit integrated circuits, to effectively utilize the normal elements in the unit integrated circuits. Further, an improved arrangement for hierarchically connecting together the outputs of all the unit circuit blocks is provided which reduces the signal line load for the memory device.
