Memory systems and devices including examples of accessing memory and generating access codes using an authenticated stream cipher

A method, comprising:

• obtaining, from a host computing device, a memory read request associated with a plurality of memory devices, the memory read request comprising a memory address;
• responsive to the memory read request:
• reading, at the memory address, data associated with the memory read request as ciphertext;
• concurrently, utilizing the memory address as an initialization vector for an authenticated stream cipher to generate an access code;
• performing a read operation associated with the memory read request using the access code;
• and
• concurrent to utilizing the memory address as the initialization vector, performing address translation using the memory read request and the memory address to translate a logical memory address of the memory address to a physical memory address, wherein the read operation is performed using the physical memory address.

An apparatus comprising:

• authentication logic circuitry configured to receive a command and an address, wherein the authentication logic circuitry is further configured to utilize the address as an initialization vector for a stream cipher to generate an access code;
• and
• translation logic circuitry configured to, concurrent with utilization of the address as the initialization vector, perform address translation using the command and the address to translate a logical memory address of the address to a physical memory address;
• a cache configured to store data associated with the command;
• and
• a plurality of memory devices, wherein at least one memory device of the plurality of memory devices is configured to perform a memory access operation associated with the command using the access code and the physical memory address.
