Enforcing system intentions during memory scheduling

摘要

A memory controller receives memory access requests from a host terminal, the memory access requests from the host terminal including one or both of host read requests and host write requests. The memory controller generates memory access requests. Priorities are assigned to the memory access requests. The memory access requests are segregated to memory unit queues of at least one set of memory unit queues, the set of memory unit queues associated with a memory unit. Each memory access request is sent to the memory unit according to a priority and an assigned memory unit queue of the memory access request.

主权项

1. A method comprising:
receiving first memory access requests generated by a memory controller; receiving second memory access requests from a host terminal; sending the first and second memory access requests to two or more memory units, wherein each of the memory units are associated with a dedicated queue set, each dedicated queue set comprising first and second queues into which the respective first and second memory access requests are placed; and sending the first and second memory access requests to the memory units according to a ratio of the first and second memory access requests, the ratio defining relative priorities of the first and second queues.
