Authenticated reading of memory system data

A memory system, comprising:

• one or more memory arrays;
• and
• processing circuitry coupled with the one or more memory arrays and configured to cause the memory system to:
• receive a signed read command requesting data from a partition of the one or more memory arrays, the signed read command including a signature generated by performing a hash procedure using a first public key;
• authenticate the signed read command by performing the hash procedure using a second public key stored in the one or more memory arrays of the memory system, wherein a public key table provides a mapping of one or more public keys to one or more host systems and to one or more partitions of the one or more memory arrays including the partition;
• retrieve the data from the partition of the one or more memory arrays in response to the signature of the signed read command matching the hash procedure using the second public key;
• and
• transmit a response to the signed read command, the response including the data retrieved from the partition.

A non-transitory computer-readable medium storing code comprising instructions which, when executed by processing circuitry of a memory system, cause the memory system to:

• receive a signed read command requesting data from a partition of one or more memory arrays of the memory system, the signed read command including a signature generated by performing a hash procedure using a first public key;
• authenticate the signed read command by performing the hash procedure using a second public key stored in the one or more memory arrays of the memory system, wherein a public key table provides a mapping of one or more public keys to one or more host systems and to one or more partitions of the one or more memory arrays including the partition;
• retrieve the data from the partition of the one or more memory arrays in response to the signature of the signed read command matching the hash procedure using the second public key;
• and
• transmit a response to the signed read command, the response including the data retrieved from the partition.

A method for memory operations at a memory system, comprising:

• receiving a signed read command requesting data from a partition of one or more memory arrays of the memory system, the signed read command including a signature generated by performing a hash procedure using a first public key;
• authenticating the signed read command by performing the hash procedure using a second public key stored in the one or more memory arrays of the memory system, wherein a public key table provides a mapping of one or more public keys to one or more host systems and to one or more partitions of the one or more memory arrays including the partition;
• retrieving the data from the partition of the one or more memory arrays in response to the signature of the signed read command matching the hash procedure using the second public key;
• and
• transmitting a response to the signed read command, the response including the data retrieved from the partition.
