An image decoding and display device includes a frame memory interface (3) and a frame memory (5). The frame memory (5) has a bank 0, a bank 1, a bank 2. The bank 2 is made up of plural sectors (sector 0, . . . , and sector N). Under a dynamic mapping mode, the frame memory interface (3) refers a sector information table (32) including sector use information in order to search and fetch an unused sector. The frame memory interface (3) allocates the unused sector in the bank 2 when decoded image data are written into the bank 2, and release the used sector when the decoded image data are read from the bank 2.
