Abstract
Input/output terminals of a first semiconductor memory device in which failures or defects exist in units of memory mats and input/output terminals of a second semiconductor memory device having redundant memory mats are connected to one another on a mounted substrate to thereby relieve the failures in the memory mat units. A power source is substantially cut off from supplying to a faulty memory mat.
