Claim:
1. A fault-tolerance through silicon via interface, wherein the fault-tolerance through silicon via interface is disposed in a three-dimensional random access memory with N memory layers and M data access path sets, each of the memory layers contains K memory arrays, each of the data access path sets contains a plurality of through silicon via paths connecting to the N memory layers, and the fault-tolerance through silicon via interface comprises: a path controlling unit, detecting and controlling the M data access path sets; and a processing unit, wherein when a fault occurs in any of the data access path sets connecting to one of the N memory layers, two or more different fault-tolerance access configurations are provided; in each of the fault-tolerance access configurations, μ, data access path sets are enabled to access all K memory arrays on one of the N memory layers, where 0<μ<M; in the two or more different fault-tolerance access configurations, all of the K memory arrays in each of the N memory layers are accessed even if one of the through silicon via paths is failed.
