Abstract: A memory system includes a plurality of first signal lines to connect a plurality of memory devices to one another. The memory devices include a first memory device and at least one second memory device. The first memory device has at least one fuse cell and outputs fuse information set based on whether each of the at least one fuse cell is programmed. The at least one second memory device receives the fuse information and selectively activates the first signal lines based on the fuse information. The at least one second memory device simultaneously operates based on the fuse information received from the first memory device.
