Interworking method external device and storage device

Abstract

The present disclosure relates to a memory controller which supports an interworking method for a test between an external device and a storage device, and a host. The memory controller proposed in the present disclosure may include a first interface configured to communicate with an external device, a second interface configured to communicate with a memory, a command queue configured to store commands received from the external device and a processor configured to perform a control operation according to a command stored in the command queue, and suspend the performance of the control operation according to the command for a waiting time corresponding to a value of a mutex counter for the command, when a mutex flag for the command is activated.

Dependencies are inferred from the claim text.
