Abstract
The semiconductor integrated circuit comprises a parallel-serial converter for converting parallel data read from memory cells into serial data and a switch control circuit for receiving a control signal and controlling the parallel-serial converter. The parallel-serial converter has a plurality of switches connected in a predetermined order. The switch control circuit controls the order of connecting the switches in accordance with the control signal so that parallel data are converted into serial data in a predetermined bit order. This minimizes delay elements formed on the transmission paths of parallel data. Specifically, for example, it eliminates the need for a conversion circuit for changing the bit order of parallel data. This results in faster data read operations from memory cells. Each of the switches in the parallel-serial converter operates in synchronization with a clock signal supplied from the exterior. This can heighten the speed of read operations, for example, in a clock-synchronous type of semiconductor integrated circuit having memory cells.
