摘要：
A semiconductor memory having a memory array, a first and a second selection line which are connected to a memory cell, and a selection means which selects either one of the selection lines. The selection means includes a selection circuit which optionally selects the first selection line or the second selection line when an address signal corresponding to the first selection line is aligned with a predetermined address signal.
