OPERATION METHOD OF STORAGE DEVICE, OPERATION METHO OF HOST DEVICE, AND OPERATION METHOD OF USER SYSTEM INCLUDING STORAGE DEVICE AND HOST DEVICE

摘要

An operation method is for a storage device that includes a storing unit storing a plurality of error logs and a physical layer and exchanges an electrical signal with a host via the physical layer. The operation method includes receiving a debugging command from the host, setting a first value at a first attribute included in the physical layer in response to the debugging command, setting a second value different from the first value at the first attribute in response to a control of the host, setting one among the plurality of error logs at a second attribute based on the first attribute at which the second value is set, and transmitting the error log set at the second attribute to the host in response to a control of the host.
