US 2026/0093841 A1 · SECURITY MANAGEMENT MODES OF A MULTI-PORT MEMORY SYSTEM

Abstract

Methods, systems, and devices for security management modes of a multi-port memory system are described. A multi-port memory system may be configured to operate according to one or more security modes that adjust access by host systems to the multiple ports of the memory system. For example, in a first mode, which may be referred to herein as a port security management mode, the memory system may restrict access by unauthenticated host systems to ports of the memory system, such that any unauthenticated host systems have no access to the memory system via the ports or are limited to a relatively primitive set of commands until the host systems are authenticated. In a second mode, which may be referred to herein as an operational mode, any host systems coupled with ports of the memory system are granted, without authentication, full access to a command set supported by the memory system.

Claims23

Dependent claims

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:
enter, based at least in part on a bootup sequence associated with the memory system, a port security management mode associated with reduced access, to the memory system, by one or more host systems prior to authentication of the one or more host systems with the memory system, wherein the one or more host systems are individually coupled with the memory system via one or more ports of the memory system;
receive, from a first host system of the one or more host systems via a first port of the one or more ports, one or more commands that request increased access for at least a second host system of the one or more host systems, wherein the second host system is coupled with the memory system via a second port of the one or more ports of the memory system;
and
grant the increased access for at least the second host system that is coupled with the memory system via the second port based at least in part on the one or more commands from the first host system.

4 more elements

A non-transitory computer-readable medium storing code, the code comprising instructions executable by one or more processors to:

enter, based at least in part on a bootup sequence associated with a memory system, a port security management mode associated with reduced access, to the memory system, by one or more host systems prior to authentication of the one or more host systems with the memory system, wherein the one or more host systems are individually coupled with the memory system via one or more ports of the memory system;
receive, from a first host system of the one or more host systems via a first port of the one or more ports, one or more commands that request increased access for at least a second host system of the one or more host systems, wherein the second host system is coupled with the memory system via a second port of the one or more ports of the memory system;
and
grant the increased access for at least the second host system that is coupled with the memory system via the second port based at least in part on the one or more commands from the first host system.
