Abstract:
1. A memory device, comprising: an interface configured to communicate with a host device in a first access mode and a second access mode, the second access mode being differently defined from the first access mode; a nonvolatile semiconductor memory configured to store a second device driver to access to the memory device in the second access mode without storing a first device driver to access to the memory device in the first access mode; and a controller configured to output the second device driver to the host device via the interface in the first access mode by emulating a device accessible by the first device driver and known to the host device, wherein the controller is configured to output data stored in the nonvolatile semiconductor memory via the interface to the host device in the second access mode after outputting the second device driver to the host device, and the second access mode converts an externally received first address into a second address and reads the data from the nonvolatile semiconductor memory based on the second address.
