Methods, systems, and devices for cache management in a memory subsystem are described. An interface controller may include a first buffer and a second buffer. The interface controller may use the first and second buffers to facilitate operating a volatile memory as a cache for a non-volatile memory. During an access operation, the interface controller may use the buffer to transfer data between the volatile memory, non-volatile memory, and another device. In response to the access operation, the interface controller may use the second buffer to transfer second data from the volatile memory to the non-volatile memory.

Cache management in a memory subsystem

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.
