Abstract
A buffer integrated circuit (IC) chip is disclosed. The buffer IC chip includes host interface circuitry to receive a request from at least one host. The request includes at least one command to access a memory. Memory interface circuitry couples to the memory. Message authentication circuitry performs a verification operation on the received request. Selective containment circuitry, during a containment mode of operation, (1) inhibits changes to the memory in response to the at least one command until completion of the verification operation, and (2) during performance of the verification operation, carries out at least one non-memory modifying sub-operation associated with the at least one command.
