Security function management within a multi-port memory system

A memory system, comprising:

• one or more memory devices;
• and
• processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
• receive, from a management operating system, a namespace configuration that indicates an allocation of one or more logical address ranges of the memory system to one or more ports of a plurality of ports of the memory system, wherein each port of the plurality of ports is coupled with a respective host system of a plurality of host systems;
• receive, from a first host system of the plurality of host systems based at least in part on the namespace configuration, a request to unlock a first logical address range, of the one or more logical address ranges, that comprises data associated with the first host system, wherein the request comprises a communication identifier associated with the first host system;
• and
• authorize, based at least in part on the request and the communication identifier of the first host system, the first host system to access the data within a first namespace comprising the first logical address range.

A first host system, comprising:

• processing circuitry associated with one or more memory devices and configured to cause the first host system to:
• perform an authorization process to authorize the first host system for security management of a memory system;
• transmit, based at least in part on the authorization process, a namespace configuration that indicates an allocation of a plurality of logical address ranges of the memory system to one or more ports of a plurality of ports of the memory system;
• receive, from a second host system, a request to unlock one or more logical address ranges of the plurality of logical address ranges for access by the second host system;
• and
• transmit, to the memory system based at least in part on the request and the namespace configuration, a command to permit access, by the second host system, to the one or more logical address ranges.

A method by a memory system, comprising:

• receiving, from a management operating system, a namespace configuration that indicates an allocation of one or more logical address ranges of the memory system to one or more ports of a plurality of ports of the memory system, wherein each port of the plurality of ports is coupled with a respective host system of a plurality of host systems;
• receiving an unlock command that requests access, by at least a first host system of the plurality of host systems, to at least one logical address range of the one or more logical address ranges allocated via the namespace configuration;
• receiving, from the first host system based at least in part on the unlock command, an access command for data stored within the at least one logical address range;
• and
• accessing the data stored within the at least one logical address range based at least in part on the access command.

A method by a memory system, comprising:

• receiving, from a management operating system, a namespace configuration that indicates an allocation of one or more logical address ranges of the memory system to one or more ports of a plurality of ports of the memory system, wherein each port of the plurality of ports is coupled with a respective host system of a plurality of host systems;
• receiving, from a first host system of the plurality of host systems based at least in part on the namespace configuration, a request to unlock a first logical address range, of the one or more logical address ranges, that comprises data associated with the first host system, wherein the request comprises a communication identifier associated with the first host system;
• and
• authorizing, based at least in part on the request and the communication identifier of the first host system, the first host system to access the data within a first namespace comprising the first logical address range.
