Nonvolatile memory device and data storage device including the same

A nonvolatile memory device comprising:

• a memory cell array;
• a control logic suitable for controlling an operation such that data is stored in the memory cell array or data is read from the memory cell array;
• and
• a state information transmission block suitable for generating a state information frame based on state information provided by the control logic, and transmitting the state information frame through a state information line to an exterior device.

A data storage apparatus comprising:

• a single state information line;
• a plurality of memory devices respectively coupled to the single state information line and suitable for transmitting state information thereof through the single state information line;
• and
• a controller suitable for receiving the state information of each of the plurality of memory devices through the single state information line, wherein
• each of the plurality of memory devices transmits the state information thereof through the single state information line according to a serial data communication scheme based on identification information and a number of transmissions of all the state information of the plurality of memory devices.
