Enhanced auto-precharge memory scheduling policy

A method comprising:

• receiving memory requests;
• storing the memory requests in a memory request queue (MRQ);
• selecting a memory request from the MRQ;
• determining when there is a memory pending request to a different page of a same bank of the memory;
• when there is a memory pending request to a different paged of a same bank of the memory, sending a combined column address strobe (CAS) signal and auto precharge signal to the memory for the memory request;
• and
• when there is not a memory pending request to a different page of a same bank of the memory, sending only a CAS signal and allow the page close timer to close the page.

A apparatus comprising:

• a core to generate memory requests;
• a memory controller comprising:
• a memory request queue (MRQ) to enqueue generated memory requests,
• a page close timer to close an activated row after passage of a threshold amount of time without any access thereto, and
• a scheduler to:
• select a memory request from the MRQ,
• determine when there is a memory pending request to a different page of a same bank of the memory,
• when there is a memory pending request to a different page of a same bank of the memory, send a combined column address strobe (CAS) signal and auto precharge signal (AP) to the memory for the memory request, and
• when there is not a memory pending request to a different page of a same bank of the memory, send only a CAS signal and allow the page close timer to close the page.
