Samsung patents memory manager that frees up space for busy chips
Samsung has patented a method for managing data flow in a computer's memory controller. The system monitors how much space different parts of the chip are using and moves requests to a backup buffer if one part is using too much room.
In the filing’s own words
A system and a method are disclosed for managing memory requests in a memory controller. The method includes storing a memory request in a request queue, the request queue comprising one or more request slots; determining if the memory request in the request queue is oversubscribed to a dedicated number of the request slots of a first information processor (IP); and copying the memory request from the request queue to a replay buffer comprising one or more replay slots in a case in which the memory request is oversubscribed to the first IP.
What exactly they claim (claim 1)
1. A memory controller comprising: a request queue comprising one or more request slots; a replay buffer comprising one or more replay slots; and circuitry configured to: determine a memory request in the request queue is oversubscribed to a dedicated number of the request slots of a first information processor (IP), and copy the memory request from the request queue to the replay buffer in a case in which the memory request is oversubscribed to the first IP.
