专利汇可以提供Semiconductor storage device专利检索,专利查询,专利分析的服务。并且PURPOSE: To simplify the control and to reduce the burden on a graphic processing unit by generating respective reset signals and counting-up clocks of a column system and a row system based on a clock and horizontal and vertical synchronizing signals according with the display dot rate.
CONSTITUTION: A timing signal SYC of a timing generating circuit STG and a timing signal ϕ
y of a timing generating circuit RTG go to the high level in accordance with a horizontal signal HSYC from a display device DPLY. This signal ϕ
y is the reset signal to reset a column address decoder CAD. Word lines of a semiconductor storage device MARY are successively selected by the decoder CAD with the counting-up clock passing a column address buffer CAB to which a clock A
0 to A
i according with the display dot rate from a graphic processing unit GPU is supplied, and data lines are selected in the same manner, and memory cells at intersections between both lines are extracted to control the display on the display device. Thus, the control of the array MARY is simplified and the burden on the graphic processing unit is reduced to increase the processing speed.
