Abstract
A memory controller performs a self-test operation on a memory device in response to a diagnostic command received from a host. The controller includes a host interface that receives the diagnostic command and a processor that executes the self-test and generates a corresponding response. The response transmitted to the host includes a basic header segment used in standard protocol communication and an extra header segment that carries result information indicating the outcome of the self-test. This structure enables efficient diagnostic communication between the host and the memory controller without disrupting regular memory operations.
