Abstract: Dynamically adjusting memory allocations based on Quality-of-Service (QoS) pool threshold values in processor-based devices is disclosed herein. In one exemplary embodiment, a processor-based device provides a storage controller circuit communicatively coupled to a memory device. The storage controller circuit comprises a dedicated storage device and a plurality of pool threshold values corresponding to a plurality of pools, wherein each pool corresponds to one or more QoS levels, and each pool threshold value defines an allocation of the dedicated storage device for the corresponding pool. For each pool of the plurality of pools, the storage controller circuit collects a usage statistic during a sampling period, and determines, based on the usage statistic, whether to modify the pool threshold value corresponding to the pool.
