A memory chip having fast access to pixel data of graphics image to be stored therein is described. The memory chip consists of data inputs and outputs (I/Os) divided into a plurality of blocks; memory arrays for storing data received from or sent to the I/Os, which are divided into the same number of blocks as the I/Os; and address input terminals for specifying addresses to be accessed by respective blocks of the memory arrays, which are divided into the same number of blocks as the memory arrays. The memory chip and the method for storing data enable reading data in a vertical line, in a diagonal line, and the like, at the same access speed as data in a horizontal line is being read. Furthermore, power consumption of the chip is significantly reduced, and the wiring arrangement of the I/Os is greatly simplified.
