Abstract
A system includes a bus, at least one processor coupled to the bus, and a storage device coupled to the bus. The storage device includes storage class memory, a buffer; and a controller. The controller is configured to receive an instruction to provide data to the bus. Responsive to receiving the instruction to provide data to the bus, the controller is configured to retrieve data from the storage class memory, update the buffer to represent the data retrieved from the storage class memory, and output, at the bus, an indication that data responsive to the instruction to provide data to the bus is available at the buffer. The at least one processor is configured to refrain from modifying local data corresponding to the instruction to provide data to the bus after the controller receives the instruction to provide data to the bus and before the controller outputs the indication.
