INTERNAL STORAGE, EXTERNAL STORAGE CAPABLE OF COMMUNICATING WITH THE SAME, AND DATA PROCESSING SYSTEM INCLUDING THE STORAGES
First Claim
1. A memory controller configured to share a function of one of an internal storage and an external storage in a union mode in which the external storage and the internal storage are logically unified with each other,wherein the memory controller is configured to translate a logical address into a physical address based on a global mapping table which maps the logical address to the physical address of each of the internal storage and the external storage and is further configured to determine which of the internal storage and the external storage processes data transmitted from a host.

17. A data processing system comprising:
-
an external storage provided external to an electronic device; an internal storage included in the electronic device; and a memory controller configured to share a function of one of the internal storage and the external storage in a union mode in which the external storage and the internal storage are logically unified with each other, wherein the function is performed by a hardware component which is one selected from an encryption engine, a random access memory (RAM), and a flash memory.

18. An electronic device, comprising:
-
a first nonvolatile memory installed in the electronic device; and a memory controller configured to enable a functionality of the first nonvolatile memory to be shared among a second nonvolatile memory for reading data from or writing data to the first nonvolatile memory and the second nonvolatile memory using the functionality, wherein the second nonvolatile memory is configured to be inserted into the electronic device, and wherein the functionality comprises at least one of encrypting and encoding the data. - View Dependent Claims (19)
