Abstract
A storage device includes a nonvolatile memory device that detects loop counts of state pass loops of at least one target state of a plurality of target states, and generates state loop count information (SLCI) indicative of whether a program operation is successful based on the detected loop count of the state pass loops, during a program operation of selected memory cells; and a storage controller that makes a request to the nonvolatile memory device for the state loop count information in response to detection of an operation condition or an external command, and assigns a memory block in which the selected memory cells are included as a bad block based on the state loop count information from the nonvolatile memory device.
