METHOD AND APPARATUS FOR CONTROLLING THE DATA WRITE IN GRAPHIC MEMORY

摘要

PURPOSE: A data write control method of a graphic memory and an apparatus thereof are provided to reduce additional costs by using the graphic memory used for a conventional display driver IC design. CONSTITUTION: A graphic memory(30) includes four memory areas(31~34). Data written in each memory area is delivered to a source driver(60). The data is read by each data read clock. A remapped address signal is applied to a graphic memory controller(10) in a feedback mode. According to display data and clock signals received from an external host, the graphic memory controller maps the address signal of the continuous data. The continuous data is written in different memory areas. A write clock, a chip select signal, display data, a page address signal, a column address signal and a latch clock are delivered to a memory mapper(20).
