Abstract
A memory controller circuit coupled to multiple memory circuits may receive requests to access particular locations within the multiple memory circuits. A request may be assigned a particular quality-of-service level. During operation, the memory controller circuit may reallocate the quality-of-service level of a particular request to a new quality-of-service level based on accumulated bandwidth credits associated with the new quality-of-service level.
