Abstract
According to the embodiments, an external storage device switches to an interface controller for supporting only a read operation of nonvolatile memory when a shift condition for shifting to a read only mode is met. A host device switches to an interface driver for supporting only the read operation of the nonvolatile memory when determining to recognize as read only memory based on information acquired from the external storage device.
Claims15
(canceled)
A storage medium storing a control program loaded in a information processing device, connected with an storage device including readable and writable nonvolatile memory, the information processing device including an interface driver for operating the storage device, the interface driver enabling a first interface driver for supporting read and write operations of the nonvolatile memory and a second interface driver for supporting only the read operation of the read and write operations of the nonvolatile memory to be alternately selected;
- wherein
- the control program determines whether or not the nonvolatile memory is to be recognized as read only memory in which only the read operation of the read and write operations is possible based on information acquired from the storage device, and switching the interface driver from the first interface driver to the second interface driver when determined to recognize as the read only memory is arranged.
