Abstract
Methods, systems, and devices for cache metadata management in a memory subsystem are described. The memory subsystem may include an interface controller coupled with a non-volatile memory and a volatile memory. The interface controller may use metadata, such as validity information and dirty information, to operate the volatile memory as cache. The interface controller may store the dirty information in the volatile memory and may store the validity information in an array in the interface controller.
