1. A method for operating a memory system, comprising:
identifying, upon issuance of a command abort signal for aborting a command queued in the memory system, a current state of the command;
receiving, by the memory system, one or more input/output (IO) packets corresponding to the current state of the command until a predetermined threshold corresponding to the command is reached, wherein the predetermined threshold is determined based on a type of the command and a number of already received IO packets; and
generating, upon determining that the predetermined threshold corresponding to the command has been reached, a response signal to indicate the command has been successfully completed without performing operations corresponding to the command on the one or more IO packets through a normal command path, wherein the response signal is generated during a power loss protection (PLP) loopback operation that simulates normal command completion without executing the command on the memory system.
