Method of write to graphic memory where memory cells designated by plurality of addresses selected simultaneously for one row address are written

Abstract

In a method of write to a graphic memory where memory cells designated by a plurality of addresses selected simultaneously for one ROW address, the present method of write includes a first step of dividing the area corresponding to the column addresses designated by one row address of a memory cell array in to a plurality of segments each consisting of an arbitrary number of column addresses, a second step of designating a start address and an end address for each of the plurality of segments based on a first piece of information of column information, a third step of specifying the section designated by the start address and the end address as the candidate for the write object areas, and a fourth step of selecting segments having write object areas based on a second piece of information of the column address information, and writing specified data to the candidate for the write object areas of the segments having the write object areas.
