A raster scan type CRT display system is disclosed which has a randomly accessable refresh memory. The display system comprises column and row start address registers for defining a read start address for the refresh memory, column and row address counters for counting the contents of the column and row start address registers as start positions to generate a read address of the refresh memory for display, column and row cursor registors for defining a data entry position on a CRT screen, and column and row address generators for generating an entry address for the refresh memory based on the contents of the column and row start address registers and the contents of the column and row cursor registers, whereby a rolling or shifting of the image is effected and the refresh memory can be accessed by a processor for read/write operation without the need to monitor the image rolling.
