Abstract
A memory array is divided into a plurality of blocks. A plurality of mode storage units is so disposed as to correspond to the memory blocks. When a plurality of controllers outputs a mode setting instruction at the time of making of power, a setting unitsets control information designated by the mode setting instruction to the corresponding mode storage unit. When different controllers gain access to a synchronous DRAM, an access operation is executed for the corresponding memory block in accordance with the control information.
