MEMORY SYSTEM AND SIGNAL TRANSMITTING AND RECEIVING METHOD OF THE SAME

摘要

A memory system and a signal transmitting/receiving method thereof are provided to enable high speed signal transmission by minimizing delay during signal transmission by reducing line loading of signal transmission lines. In a memory system comprising a memory control part(100), first memory modules(200-1) and second memory modules(200-2) transmit/receive data to/from the memory control part. Each memory module includes a first memory and a second memory, and the first memory outputs a control signal applied from the memory control part to the second memory, and the second memory receives read data output from the first memory and then outputs the read data to the memory control part. The control signal output from the memory control part is transmitted to the first memory of the first and the second memory modules in common through a control signal line, and the read data output from the second memory of the first memory module is transmitted to the memory control part through a first read data line, and the read data output from the second memory of the second memory module is transmitted to the memory control part through a second read data line.
