Abstract
A processing or memory device may include a first encryption pipeline to encrypt and decrypt data with a first encryption mode and a second encryption pipeline to encrypt and decrypt data with a second encryption mode, wherein the first encryption pipeline and the second encryption pipeline share a single, shared pipeline for a majority of encryption and decryption operations performed by the first encryption pipeline and by the second encryption pipeline. A controller (and/or other logic) may direct selection of encrypted (or decrypted) data from the first and second encryption pipelines responsive to a region of memory to which a physical address of a memory request is directed. The result of the selection may result in bypassing encryption/decryption or encrypting/decrypting the data according to the first encryption mode or the second encryption mode. More than two encryption modes are envisioned.
