ABSTRACT:
Techniques to indicate whether datum transferred from a memory device to a second device is likely to be accessed again by the second device. The second device may include a buffer memory to store the datum when the datum is indicated as likely to be accessed again. If the second device is to access the datum again after receipt from the memory device, the second device may retrieve the datum from the buffer memory instead of from the memory device. Accordingly, multiple accessed of datum transferred once from an external memory are possible.
