Abstract
An output drive circuit is constructed by an output driving MOS transistor driving an output node in accordance with an internal read data, a termination controlling P-channel MOS transistor selectively rendered conductive in accordance with the internal read data when the output driving MOS transistor is non-conductive, and a P-channel MOS transistor rendered conductive to pull up the output node to a power supply voltage level at least when the output drive circuit is inactive. Data transfer is executed in an open drain manner, and the P-channel MOS transistor is utilized as a transistor for termination bus line. Data/signal is transferred fast in an active termination scheme with low current consumption, and an area occupied by the output drive circuit is reduced.
