Description

ABSTRACT:
A semiconductor integrated circuit device of the present invention includes a plurality of banks and a plurality of sense amplifier bands. A switch circuit included in each sense amplifier band receives a signal on a transmission line and outputs a signal read from the bank to a global data input/output line arranged in the column direction. A column bank control circuit for outputting a column bank control signal is arranged on the column decoder side. The column bank control signal is supplied to the transmission line through a column bank control signal line arranged in the column direction. The switch circuit operates in accordance with the column bank control signal. By such a configuration, a column-related operation can be matched easily.
