Abstract: DDR_SDRAM chips running at 1.5 clock rate are used for transferring image data from an image data source to a source driver in a display panel. In general, P DDR_SDRAM chips running at a 1.5 clock rate are used to store frame data in N frames. If the frame date in each of the N frames is n bits and the memory space in the DDR_SDRAM chip is m, then P is a smallest integer equal to or greater than N multiplied by (n/m). In data transfer in a frame, a line period is partitioned into N segments and each DDR-SDRAM chip is separated into (N?1) parts such that the parts are used to read different data in the different frames. In order to share I/O pins when using a number of DDR_SDRAM chips, the read/write sequence for the all DDR_SDRAM chips follows the same command and address.
