Abstract
A semiconductor memory includes a memory array; data buses connected to the memory array; a plurality of data transmission circuits connected to the data buses one by one; and a buffer circuit connected to an outside device. The memory further includes a gate circuit arranged between the data transmission circuits and the buffer circuit; and a fuse connected to the gate circuit. The data transmission circuits are selectively connected to the buffer circuit by controlling the fuse and the gate circuit, so that a defective element is replaced with a normal element.
