Nonvolatile memory device, data storage device including the same and operating method thereof

1. A data storage device comprising:

a nonvolatile memory device operated by first and second voltages,

the nonvolatile memory device including an operation recorder operated by the second voltage, and configured to record information on an operation being performed in the nonvolatile memory device; and

a controller configured to control the nonvolatile memory device and operated by the second voltage,

wherein the controller transmits an information request command to the nonvolatile memory device depending on whether the nonvolatile memory device is powered off, and checks an operation stopped by the power-off of the nonvolatile memory device and a performance status of the checked operation, based on the operation information received from the nonvolatile memory device,

wherein the operation recorder further comprises a recording control circuit configured to record the information on the operation which is being performed in the nonvolatile memory device, and store the recorded information in an operation information register according to control data of a control logic, and

wherein when the nonvolatile memory device is powered off, the controller transmits the information request command to the nonvolatile memory device.

2. The data storage device of claim 1 , wherein the nonvolatile memory device further comprises:

a memory cell array operated by the first voltage, and comprising a plurality of memory cells;

a peripheral circuit configured to store data in the memory cell array or read the data from the memory cell array;

an input and output (I/O) interface configured to transmit data to, and receive data from, the controller;

and

the control logic operated by the first voltage, and configured to control the peripheral circuit such that the nonvolatile memory device performs an operation corresponding to a command received from the controller, and control the operation recorder to store the information on the operation being performed in the nonvolatile memory device.

3. The data storage device of claim 2 , wherein the operation recorder comprises the operation information register configured to store the information on the operation being performed in the nonvolatile memory device.

4. The data storage device according to claim 3 , wherein when the nonvolatile memory device is recovered to a normal state from a power-off state, the controller transmits the information request command to the nonvolatile memory device.

5. An operating method of a data storage device which includes a nonvolatile memory device operated by first and second voltages, the nonvolatile memory device including an operation recorder operated by the second voltage, and configured to record information on an operation being performed in the nonvolatile memory device, and a controller operated by the second voltage, the operating method comprising:

determining whether the nonvolatile memory device is powered off;

transmitting by the controller, an information request command to the nonvolatile memory device when the nonvolatile memory device is powered off; and

checking an operation stopped by the power-off of the nonvolatile memory device and checking performance status of the operation based on operation information received from the nonvolatile memory device,

wherein the operation recorder further comprises a recording control circuit configured to record the information on the operation which is being performed in the nonvolatile memory device, and store the recorded information in an operation information register according to control data of a control logic.

6. The operating method according to claim 5 , wherein the determining of whether the nonvolatile memory device is powered off comprises:

transmitting a status request command to request processing status information on a command transmitted to the nonvolatile memory device;

determining whether the processing status information is received from the nonvolatile memory device within a set time;

transmitting an identification (ID) request command to the nonvolatile memory device when the processing status information is not received from the nonvolatile memory device within the set time; and

determining that the nonvolatile memory device is powered off, when invalid data are received from the nonvolatile memory device.

7. The operating method according to claim 5 , wherein the transmitting of the information request command to the nonvolatile memory device is performed when the nonvolatile memory device is powered off.

8. The operating method according to claim 5 , wherein the transmitting of the information request command to the nonvolatile memory device is performed when the nonvolatile memory device is recovered to a normal state from the power-off state.
