Abstract
A data storage device and a method of operating the same are provided. The data storage device includes a first non-volatile memory device, a second non-volatile memory device, and a management module. The management module receives a multi-access command including first and second physical addresses which are different from each other from a host, generates and sends a first access command including the first physical address to the first non-volatile memory device, and generates and sends a second access command including the second physical address to the second non-volatile memory device. The data storage device performs the first and second access commands on the first and second physical addresses, respectively.

1-27. (canceled)
A method of accessing a data storage device, the method comprising:
- receiving an external multi-access command at the data storage device from a device external to the data storage device, the external multi-access command including a first address and a second address;
- supplying a first access command based on the external multi-access command to a first nonvolatile memory, the first access command including the first address;
- executing a first access operation on the first nonvolatile memory using the first access command and the first address;
- supplying a second access command based on the external multi-access command to a second nonvolatile memory, the second access command including the second address;
- and
- executing a second access operation on the second nonvolatile memory using the second access command and the second address.
The method of 28, wherein:
- the first address is a first physical address;
- and
- the second address is a second physical address.
A multi-access method for a data storage device, the method comprising:
- initiating a multi-access operation on a host device by generating a multi-access request;
- performing a mapping operation on the multi-access request to generate a multi- access command, the multi-access command including at least a command type indicator, a duplicate/split flag, and a plurality of addresses;
- and
- sending the multi-access command from the host device to the data storage device.
A multi-access method for a data storage device including a management circuit and a plurality of nonvolatile memory devices, the multi-access method comprising:
- receiving an external multi-access command from a device external to the data storage device, the external multi-access command including a command type indicator and at least a first address and a second address;
- transmitting a first internal multi-access command based on the external multi- access command to a first nonvolatile memory device of the data storage device using the first address;
- transmitting a second internal multi-access command based on the external multi-access command to a second nonvolatile memory device of the data storage device using the second address;
- accessing the first nonvolatile memory device using the first address;
- and
- accessing the second nonvolatile memory device using the second address.
