Abstract
A semiconductor device includes a memory cell array including a plurality of memory array basic units. A first bus for transfer of address/control signals, includes a first buffer circuit operating as a pipeline register. A second bus for bidirectional transfer of write/read data, includes a second buffer circuit operating as a pipeline register. A first control circuit sequentially sends the address/control signals on the first bus, and a second control circuit sequentially sends/receives write/read data on the second bus.
