Abstract
Methods, apparatuses, and computer program products for memory access to a dual in-line memory module (DIMM) form factor flash memory are provided. Embodiments include receiving, by a controller from a processor through cacheable memory in the processor, a read request; transmitting, by the controller, the read request to the DIMM form factor flash memory; polling, by the controller, a read queue in the DIMM form factor flash memory until data is ready for the read request; copying from the DIMM form factor flash memory, by the controller, the data corresponding to the read request to a read queue in the controller; transmitting, by the controller on an interface between the controller and the processor, an invalidate command for the cacheable memory; and in response to receiving the invalidate command, reading by the processor the data stored in the read queue in the controller.
