Abstract

A request is received to program host data to a memory device of a memory sub-system. The host data is associated with a logical address. A redundancy factor that corresponds to the logical address associated with the host data is obtained. A first physical address associated with a first set of cells of the memory device and a second physical address associated with a second set of cells of the memory device are determined based on the redundancy factor. The first set of memory cells is to store the host data and the second set of memory cells is to store redundancy metadata associated with the host data. The host data is programmed to the first set of memory cells. The redundancy metadata associated with the host data is programmed to the second set of memory cells.
