    摘要： An image memory, image memory system, memory controller and semiconductor integrated circuit that are capable of efficiently accessing a rectangular area of two-dimensionally arrayed data are provided. The semiconductor integrated circuit device in which circuits are integrated on a semiconductor substrate, the semiconductor integrated circuit device comprising: an image processing controller (81) for decoding coded image data; a memory controller (82) for controlling an image memory (86); and a setting register (543) for setting function information that indicates a function the image memory has, wherein the image processing controller (81) outputs information on a coordinate of an origin in a rectangular image and size information on the length and width of the rectangular image, to the memory controller (82), and the memory controller (82) generates commands, addresses, and a start byte signal for accessing the image memory (86), on the basis of the information on the coordinate of the origin, the size information on the length and width, and set information that is set in the setting register (543), the start byte signal indicating a start position of a memory unit area (45) within the image memory (86), which is selected by the address.
