A method for controlling a memory device includes: categorizing a plurality of sub-memory units of the memory device into a first group of sub-memory units and a second group of sub-memory units; sequentially storing pixel data of a plurality of pixels being displayed on a first line of a display screen into the sub-memory units of the first group of sub-memory units; sequentially storing the pixel data of a plurality of pixels being displayed on a second line next to the first line of the display screen into the sub-memory units of the second group of sub-memory units; and, starting from a next but one sub-memory unit to the first selected sub-memory unit, sequentially storing the pixel data of a plurality of pixels being displayed on a third line next to the second line of the display screen into the sub-memory units of the first group of sub-memory units.

Apparatus for controlling memory device and related method

A graphics display device comprises a first and second memory, and a data transfer controller coupled with the first and second memory. In some embodiments, a method of storing pixel data comprises receiving and latching first pixel data associated with a first pixel, receiving second pixel data associated with a second pixel, and concurrently writing the first pixel data in the first memory and the second pixel data in the second memory. In other embodiments, a method of accessing pixel data of an image frame comprises accessing the first and second memory for reading out pixel data of each pair of adjacent pixels, when the image frame has an odd total number of pixels determining whether a final pixel data is in a latched state, and reading out the final pixel data from the data transfer controller when the final pixel data is in the latched state.
