Abstract

Data associated with a memory device may be authenticated before an associated operation is executed. The data may be authenticated before it is executed at a volatile memory. The data may be associated with a hash (e.g., a first hash) and may be communicated from the memory device to a host device. At the host device, the data and the first hash may be written (e.g., stored) to temporary storage, such as a cache. Once stored to the cache, the host device may generate an additional hash (e.g., a second hash) related to the data using a key inaccessible to the memory device. If the first hash and second hash match, the data may be authenticated and one or more operations may be executed.
