Abstract
PURPOSE:To designate an optional address and to access said address regardless of the number of data bytes to be accessed, by allocating the memory bank output to the most significant or least significant byte of a data bus to a memory bank having no idle area and then allocating the following memory bank outputs successively to the following positions of the data bus. CONSTITUTION:The memory bank output (byte unit) corresponding to a designated address given from a CPU to the most significant or least significant byte of a data bus DB having the width equal to plural bytes is allocated to the memory banks 10-13 having no idle area. Hereafter the following bank outputs are successively allocated to the following positions of the bus DB respectively. Thus it is possible to designate an optional address regardless of the number of data bytes to be accessed and to access the banks 10-13.
