PURPOSE: A sense amp circuit is provided to secure an area margin of a sense amp circuit part by dividing and arranging a transistor for transferring data. CONSTITUTION: A sense amp part(C) senses and amplifies the electric potential difference of a bit line pair. A first data transmission part(A) is arranged in one side of the sense amp part based on the vertical direction of the extension direction of the bit line. The first data transmission part transfers a signal of one bit line of the bit line pair to the first data line by being connected to one of the bit line pair. A second data transmission part(B) is arranged in the other side of the sense amp part based on the vertical direction of the extension direction of the bit line. The second data transmission part transfers a signal of the rest bit line to the second data line by being connected to the rest bit line.
