Abstract: Various embodiments of methods and systems for dynamically managing the capacity utilization of a memory component in a system on a chip (“SoC”) are disclosed. Memory utilization is optimized in certain embodiments through dynamic compression and decompression within a memory subsystem. Based on parameters of the SoC that are indicative of a quality of service (“QoS”) level, a memory controller may determine that the format of the data in a write request should be converted and stored in a relinked memory address. Subsequently, a primary memory address associated with the data may be released for storage of different data. Similarly, embodiments may return data requested in a write request in a format different than that which was requested.
