Abstract
A partial memory die is removed from an edge of a wafer such that the partial memory die is missing a portion of the memory structure that was not printed on the wafer. A usable portion of the incomplete memory structure is determined and one or more rectangular zones in the usable portion of the incomplete memory structure are identified. During operation of the memory system, the memory system receives logical addresses for memory operations to be performed on the partial memory die and determines physical addresses that corresponding to the logical addresses. The memory system performs an out of bounds response for a physical address that is on the partial memory die but outside of the one or more rectangular zones. The memory system performs memory operations for physical addresses that are inside the one or more rectangular zones.
