Patent ID: 8024508

Claim:
A storage control device comprising: a flash memory-based storage including at least a first memory region storing first data for later access and a second memory region storing second data for later access; and one or more controllers configured to: enable access to the flash memory-based storage, and independently control power supplied to the memory regions by controlling switches that enable or disable power to a memory region, such that the first memory region storing the first data for later access and the second memory region storing the second data for later access are not concurrently provided power for data access, the switches being configured to disable the power when a counter has determined that the memory region has not been accessed for a predetermined period of time; a PCI express interface configured to connect the flash memory-based storage and a host through the PCI express interface; and a format converter configured to: upon receiving an indication of a memory access of the flash memory-based storage, perform data format conversion between a data format compatible with the PCI express interface and a second data format compatible with the host, upon completing the data format conversion, perform address format conversion between a first address format compatible with the PCI express interface and a second address format compatible with the host, and verify the conversion between the first and second address formats, and upon verifying a successful conversion between the first and second address formats, select one of the memory regions for reading or writing.
