Abstract

PURPOSE:To process as the same variety irrespective of the position of a faulty memory cell, by fixing a level of an address input, in hardware mode, by which a memory array is divided into two in accordance with a position where the faulty memory cell exists. CONSTITUTION:As a result of inspection, for instance, when it becomes clear that a faulty memory cell exists on an intersection point of column lines R0-R127 and row lines C0C63, an address bonding pad 12 is connected to an electric power supply bonding pad. On the contrary, when a faulty memory cell exists on an intersection point of the column lines R0-R127 and row lines C64-C127, the pad 12 is connected to a ground bonding pad. According to such a constitution, as for a memory device in which faulty memory cell exists on the row lines C0-C63, the uppermost bit AD13 of a row address buffer 3 always becomes high, therefore, only a memory cell on the intersection point of the lines R0-R127 and C64-C127 becomes significant. On the other hand, as for a memory device in which a faulty memory cell exists on the intersection point of the lines R0-R127 and C64-C127, only 1/2 becomes significant in the same way.
