  • Patent number: 9240221
    Abstract: A circuit on an end column of a divided memory array is formed by a block selection transistor having the same shape as that of a memory cell transistor. As the pattern of the connecting section between the main bit line and the sub-bit line is made in the same shape as that of the memory cell, it is possible to realize a pattern uniformity and to eliminate the need for using memory array dummy patterns.
