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.
