Secure authentication for debugging data transferred over a system management bus

Abstract:

A processing device in a memory system receives a privilege key from a host system, the privilege key having an associated level of access to debug information associated with the memory device and determines the level of access associated with the privilege key. The processing device receives, from the host system, a request for debug information directed to a debug slave address associated with a system management bus port of a memory sub-system, identifies the debug information corresponding to the level of access associated with the privilege key, and sends the debug information to the host system over a system management bus coupled to the system management bus port of the memory sub-system.
