Method of operating storage device and method of operating data processing system including the device

A method of operating a data storage device including a first memory device and a second memory device, the method comprising:

• receiving a first identifier (ID) and a virtual address from a host;
• translating the first ID and the virtual address into a first physical address;
• and
• accessing at least one of the first memory device and the second memory device based on the first physical address.

A method for operating a data storage device, the data storage device including a plurality of heterogeneous memory devices and a memory controller, the method comprising:

• receiving, using the memory controller, a memory operation instruction from a host, the memory operation including at least a process ID and a virtual address;
• translating, using the memory controller, the virtual address into a physical address associated with a memory device of the plurality of heterogeneous memory devices using a virtual address-to-physical address translation map stored on a buffer and the process ID;
• and
• performing, using the memory controller, a memory operation at the physical address on the associated memory device in accordance with the memory operation instruction.
