Nonvolatile memory device, controller for controlling the same, storage device having the same, and operating method thereof

An operating method of a controller, the operating method comprising:

• transmitting an extended status check command to a nonvolatile memory device;
• transmitting a plane bitmap value in an address cycle to the nonvolatile memory device, the plane bitmap indicating at least one plane, among a plurality of planes of the nonvolatile memory device;
• toggling a read activation signal to correspond to a number of planes indicated by the plane bitmap value;
• and
• receiving status information about the at least one plane indicated by the plane bitmap value according to a data strobe signal corresponding to the read activation signal through data lines.

A controller comprising:

• a nonvolatile memory interface circuit connected to a nonvolatile memory device through a plurality of control pins and data lines and configured to control the nonvolatile memory device;
• and
• a memory device configured to store plane number information about the nonvolatile memory device,
• wherein the nonvolatile memory interface circuit is configured to:
• transmit an extended status check command to the nonvolatile memory device to determine a plane status of the nonvolatile memory device,
• toggle a read activation signal to correspond to the plane number information, and
• receive plane status information about the nonvolatile memory device through the data lines based on a data strobe signal corresponding to toggling of the read activation signal.
