Abstract
A synchronous semiconductor memory device is utilized as an image data storage memory, and at most two pixels as one word are alternately stored in first and second banks of the synchronous semiconductor memory device. Respective pixel data of two types of color-difference signals as to the same pixel are stored in the same address position of the banks of the synchronous semiconductor memory device. Necessary data can be transferred by the burst length of the synchronous semiconductor memory device while suppressing overhead of page change to the minimum by alternately accessing the first and second banks.
