PROBLEM TO BE SOLVED: To provide a DRAM low in power consumption and low in manufacturing cost without needing an SRAM, and to provide a refresh method. SOLUTION: This DRAM 10 comprises terminals 18a, 18b to which addresses of memory blocks 16a, 16b, 16c, 16d are inputted, selectors 20a, 20b, 20c, 20d selecting T/C of addresses, and a circuit selecting a block from signal of T or C of an address outputted from the selectors 20a, 20b, 20c, 20d.
