Various embodiments include systems and methods for improving the efficiency of a memory subsystem in a computing device. The memory subsystem may be configured to detect memory access events and determining their associated timings and determine an efficiency of the memory subsystem based on operational parameters of the memory subsystem, the detecting memory access events, and associated timings. The memory subsystem may adjust the operational parameters of the memory subsystem based on the determined efficiency of the memory subsystem. The memory subsystem may dynamically modify the operations of the memory subsystem based on the adjusted operational parameters.

Metadata is dynamically relocated in a DRAM from a virtual page that does not map to the same DRAM row in which the associated data is located, to that same DRAM row. If the target of a data access request is a location in a first page that is configured to store metadata rather than data, then a second location in a second page may be determined, and the requested data may be accessed at the second location. The associated metadata may be accessed at the location in the first page, which is configured in the virtual domain to store data but is configured in the physical domain to store the metadata associated with the data in the first page.
