KLM4G1YEMD-C031
Official Samsung legacy matrix verifies exact part number, density, package size and 2013 production status. Where the MMC revision cell is blank, this database intentionally does not infer 4.5 vs 5.0.

Verify CID/EXT_CSD for eMMC or UFS descriptors/LU geometry/RPMB for UFS before donor substitution.
A matching part number or package does not prove donor compatibility. Before replacement confirm the ball map, VCC/VCCQ, protocol generation, capacity geometry, DRAM training (MCP), CID/EXT_CSD or UFS descriptors, RPMB and OEM provisioning.
