A plurality of units, each including the memory cell array block, the control transistors and control signals, are arranged. Main bit lines each passing through these units are extended so that they are connected to the select transistors of each unit pattern. In such a configuration, the capacitive load of bit lines owing to high integration of a non-volatile semiconductor memory is reduced, thereby realizing the high speed operation of the memory.
