Systems, methods, and apparatuses for implementing die recovery in Two-Level Memory (2LM) stacked die subsystems are described. A stacked semiconductor package includes a processor functional silicon die at a first layer of the stacked semiconductor package; one or more memory dies forming a corresponding one or more memory layers of the stacked semiconductor package; a plurality of Through Silicon Vias (TSV s) formed through the one or more memory dies; a plurality of physical memory interfaces electrically interfacing the one or more memory dies to the processor functional silicon die at the first layer through the memory layers via the plurality of TSVs; and a redundant physical memory interface formed by a redundant TSV traversing through the memory layers to the processor functional silicon die at the first layer through which to reroute a memory signal path from a defective physical memory interface at a defective TSV to a functional signal path traversing the redundant TSV.
