MEMORY CONTROL DEVICE, MEMORY DEVICE, AND MEMORY CONTROL METHOD

摘要

A memory control device includes: a command generation unit (102) which divides a memory access request issued from a master into access commands for respective memory devices; command issuing units (104, 105) which issue access commands to the memory devices; and a data control unit (106) which exchanges data between the master (200) and memories (0, 1) when required. The command generation unit (102) performs control to switch between a mode for outputting identical physical addresses and a mode for outputting different physical addresses to a plurality of memory devices depending on whether the physical addresses of the memory devices corresponding to the divided access commands are identical or different.
