Abstract: A storage device with multiple interfaces and multiple levels of data protection includes a first memory area and a second memory area utilizing data protection for protecting second data stored in the second memory area, the second memory area being distinct from the first memory area. The storage device also includes a first interface through which the storage device writes first data into the first memory area or reads first data stored in the first memory area and a second interface through which the storage device writes second data into the second memory area or reads second data stored in the second memory area, the second interface being distinct from the first interface. A controller controls access to the first memory area and the second memory area, and the second memory area is inaccessible through the first interface.
