Abstract
A reference column of a semiconductor memory includes a reference bit line; a reference source line; and first to Nresistive memory cells disposed between the reference bit line and the reference source line. Data of a first state is stored in the first resistive memory cell and data of a second state is stored in the Nresistive memory cell before a read operation, and the first and Nresistive memory cells form current paths between the reference bit line and the reference source line in the read operation.
