Methods to improve security of multi-tenant memory modules

Abstract

An example system includes a host computing device configured to host a first tenant and a second tenant, non-volatile memory configured to store data for the first tenant and data for the second tenant, and a memory controller including a cache of a volatile memory configured to store a first encrypted key associated with the first tenant used to access the data stored at the non-volatile memory and a second encrypted key associated with a second tenant used to access the data stored at the non-volatile memory. The memory controller further includes a processor having encryption logic configured to detect an attack on a portion of the cache storing the second encrypted key by the first tenant, and to erase the stored second encrypted key from the cache in response to detection of the attack.
