Patent ID: 11922011

Abstract:
A data item is programmed to a first set of management units (MUs) associated with a first portion of one or more memory devices. The first portion includes memory cells of a first type. The first set of MUs is associated with a first physical address. A mapping is generated in a virtual MU data structure that associates the first physical address with a set of virtual MUs associated with the one or more memory devices. An entry associated with the data item is added to a logical-to-physical (L2P) table associated with the one or more memory devices. The entry includes an identifier associated with the set of virtual MUs associated with the one or more memory devices. A detection is made that the data item is programmed to a second set of MUs associated with a second portion of the one or more memory devices. The second portion includes memory cells of a second type. The second set of MUs is associated with a second physical address. The mapping is updated to associate the set of virtual MUs with the second physical address.
