ABSTRACT:
Embodiments of a memory scoreboard are presented herein. The memory scoreboard tracks memory requests for each rank and bank of memory being addressed. When there are no pending requests, the scoreboard provides an indication to an idle timer that begins a count down to close a current page of the memory. The idle timer can be configured dynamically to close memory pages and to address dynamically-changing code streams by tracking previous decisions made on page closes.
