MEMORY SYSTEMS AND DEVICES INCLUDING EXAMPLES OF ACCESSING MEMORY AND GENERATING ACCESS CODES USING AN AUTHENTICATED STREAM CIPHER

Abstract:

Examples of systems and method described herein provide for accessing memory devices and, concurrently, generating access codes using an authenticated stream cipher at a memory controller. For example, a memory controller may use a memory access request to, concurrently, perform translation logic and/or error correction on data associated with the memory access request; while also utilizing the memory address as an initialization vector for an authenticated stream cipher to generate an access code. The error correction may be performed subsequent to address translation for a write operation (or prior to address translation for a read operation) to improve processing speed of memory access requests at a memory controller; while the memory controller also generates the encrypted access code.
