Abstract
A memory device includes a plurality of memory die blocks and a plurality of memory channels operably coupled to the plurality of memory die blocks and a memory controller configured to identify one or more memory die blocks as being invalid. The memory controller obtains a first matrix storing a mapping of memory channels to memory die blocks and creates a new mapping of memory channels to memory die blocks excluding the invalid memory die blocks. The new mapping is stored in a second matrix and one or more operations are performed on the memory die blocks based on the new mapping.
