摘要: Provided are a multi-channel package capable of reducing a test cost while performing a test at a high speed, and a test apparatus and a test method of testing the multi-channel package. The multi-channel package includes: a package substrate; and at least two semiconductor chips mounted on the package substrate and having different channels, wherein each of the at least two semiconductor chips includes a built-in-self-test (BIST) circuit and operates in one of a self-test mode, a tester mode, and a target mode during a test, and in the tester mode or the target mode, the at least two semiconductor chips are configured to be inter-channel cross-tested through an external signal path of the package substrate.
