ABSTRACT:
A two-dimensional memory unit allowing two-dimensional data to be written and read along different axes. Memory blocks having numerous memory cells arranged along each of the axes, are located at respective memory addresses, and a number of such memory blocks are arranged along the respective axes. All the memory cells of any of the memory blocks are accessed at the same time. The memory cells for actually inputting and outputting data are selected by data input and ouput controls. Data are written or read out of all of the number of memory cells in a two-dimensional small area by one memory access and, therefore, rapidly with no regard to the direction of scanning which occurs along any of the different axes.
