BUS CIRCUIT AND SEMICONDUCTOR DEVICE

摘要

A bus circuit which transfers data of a plurality of bits output from one module to another module, includes: a data bus; a division circuit configured to divide the data into a plurality of pieces of divided data including a plurality of bits in a number equal to or less than half a bit width of the data bus; an inverter circuit configured to generate a plurality of pieces of inverted divided data by inverting each of the plurality of pieces of divided data; an output circuit configured to output each of the plurality of pieces of divided data and each of the pieces of inverted divided data corresponding to each of the pieces of divided data as a data pair; and a coupling circuit configured to extract and couple the plurality of pieces of divided data from the data pair received from the data bus.
