MASTER SLICE TYPE SEMICONDUCTOR CIRCUIT DEVICE

摘要

A memory block has one memory circuit ; one conductive layer to peripheral portions of the memory circuit and used as an input portion. Power source lines are provided to the peripheral portion of the memory circuit and formed by a conductive layer different from the conductive layers at a selected input portion. The portion connected by the contact hole is set or clamped to a predetermined logic level by the power source line. This enables a change of the memory capacity or the function of the memory block to satisfy customer reguirements.
