1. A memory system, comprising:
a memory apparatus comprising a buffer die, a plurality of core dies disposed on the buffer die, a plurality of channels and a through silicon via configured to transmit a signal between the buffer die and at least one of the core dies;
a memory controller configured to output a command signal and an address signal to the memory apparatus, to output a data signal to the memory apparatus and to receive the data signal from the memory apparatus; and
an interposer comprising a plurality of channel paths for connecting the memory controller and the channels,
wherein the memory apparatus further comprises a path selector for changing a connection state between the channels and channel paths, wherein the path selector includes a multiplexer connected to at least two of the channels and at least two of the channel paths, and
wherein when an error of the memory system is detected in a first connection state between the channels and the channel paths, the path selector changes the first connection state to a second connection state between the channels and the channel paths,
wherein the buffer die is connected to the channel paths,
wherein the buffer die comprises a plurality of buffers, and
wherein the buffers are configured to output the data signal transmitted through at least one of the channel paths to at least one of the channels.
