Abstract
The semiconductor memory system includes a memory controller, N system data buses, and first through P-th memory module groups. The N system data buses are connected to the memory controller and respectively have a width of M/N bits. The first through P-th memory module groups are connected to the N system data buses and respectively have N memory modules. In each of the first through P-th memory module groups, a different one of the N system data buses is connected to each of the N memory modules, and each of the N system data buses has a data bus width of M/N bits. The first through P-th memory module groups are operated in response to first through P-th corresponding chip select signals. M is the bit-width of an entire system data bus of the semiconductor memory system. The N system data buses are wired such that data transmission times are the same from each N memory modules that operate in response to the same chip select signal to the memory controller.
