Abstract
A data output circuit and method in a synchronous semiconductor device are described. The semiconductor device is preferably a wave pipelined synchronous semiconductor device. A first-stage or former-stage latch unit receives a first bit of a group of data bits to be output. A second-stage or latter-stage latch unit receives a second bit of the group of data bits. A buffering unit is interposed between the first and second stage latch units. The buffering unit receives the second bit from the second-stage latch unit and forwards the second bit to the first-stage latch unit.
