  • Publication number: 20230359398
    Abstract: A determination is made of whether a memory sub-system operates in a full capacity mode or a reduced capacity mode. The full capacity mode corresponds to accessing data residing at a set of memory devices via a number of physical data channels that corresponds to a number of logical data channels. The reduced capacity mode corresponds to accessing the data via a number of physical data channels that is less than the number of logical data channels. A data structure is updated to include one or more mappings between physical data channels and logical data channels according to the determination. A memory access operation to access a data item at memory cells of at least one of the set of memory devices is executed based on the one or more mappings of the data structure.
