发明名称 Master slice integrated circuit having a reduced chip size and a reduced power supply noise
摘要 In a master slice integrated circuit, a number of connection pads are located in a peripheral edge region of a chip in such a manner that each one power supply pad is interposed between each pair of signal input/output pads and a number of unitary pad arrays each of which consists of a signal pad, a power supply pad and another signal pad located in the named order are repeatedly arranged along a peripheral edge of the chip. Thus, the pad pitch can be reduced to two thirds of the width of an I/O cell, without changing the I/O cell size. In addition, since the power supply pad is located adjacent each of the I/O cells, it is effective to suppress or minimize the power supply voltage noise caused by the simultaneous driving. <IMAGE>
