Patent ID: 8209502

Claim:
A semiconductor integrated circuit, comprising: at least one of a one-dimensional access process units outputting one-dimensional access information; an area detection unit detecting a main rectangular area to which an access start address indicated by the one-dimensional access information is included among a plurality of main rectangular areas corresponding to two-dimensional access information; an address conversion unit dividing the main rectangular area detected by the area detection unit into a plurality of sub rectangular areas, detecting a sub rectangular area to which the access start address indicated by the one-dimensional access information is included, and converting the one-dimensional access information into first two-dimensional access information based on a relative position of the sub rectangular area including the access start address when a start address of the main rectangular area being detected is used as a reference; at least one of a two-dimensional access process units outputting second two-dimensional access information; and a memory controller converting the first two-dimensional access information and the second two-dimensional access information into an access address to access a semiconductor memory.
