US Patent 11842059 Memory sub-system address mapping

A method includes accessing a first memory component of a memory sub-system via a first interface, accessing a second memory component of the memory sub-system via a second interface, and transferring data between the first memory component and the second memory component via the first interface. The method further includes initially writing data in the first memory component via a first address window and accessing data in the second memory component via a second address window in response to caching the data in first memory component to the second memory component, wherein caching the data in the first memory component to the second component includes changing an address for the data from the first address window to the second address window.
