Abstract: Methods, systems, and devices for word line timing management are described. In some examples, a digit line may be precharged as part of accessing a memory cell. The memory cell may include a storage component and a selection component. A word line may be coupled with the selection component, and the word line may be selected in order to couple the storage component with the digit line, by way of the selection component. The word line may be selected while the digit line is still being precharged, and the storage component may become coupled with the digit line with reduced delay after the end of precharging of the digit line, concurrent with the end of the precharging of the digit line, or while the digit line is still being charged. Related techniques for sensing a logic state stored by the memory cell are also described.

Abstract: 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.

Abstract: Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a criticality value can be determined and used as a basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a criticality value associated with performing a garbage collection operation satisfies a condition. Based on determining that the condition is satisfied, a parameter associated with performing the garbage collection operation can be adjusted. The garbage collection operation is performed on the data block stored on the memory component using the adjusted parameter.
