Abstract
In response to an output data width switching mode signal, a predecoder zone+selector zone outputs selection signals SEL to SEL and WORDA to WORDC to a preamplifier+write driver zone. The preamplifier+write driver zone can switch connection between global I/O lines GIO< > to GIO< > and a data bus in response to these selection signals. Read data is output to a pad without through a selector circuit or the like on the data bus, whereby a simple structure can be obtained with no critical adjustment of a delay time resulting from mode switching or address change.
