ABSTRACT:
A storage controller that can control memory addresses even when a memory module having a different device configuration than an already mounted memory module is added as an expansion module. More specifically, a storage controller for controlling a storage unit that can be constructed using a plurality of memory modules is configured so as to include: a register which stores memory module configuration information for a basic memory module and an expansion memory module independently of each other; and an address conversion unit which, based on the memory module configuration information stored in the register, generates an address that can access the storage unit even when the memory address space of the expansion memory module is different from the memory address space of the basic memory module.
