ABSTRACT:
A semiconductor integrated circuit is provided for performing an arithmetic operation using an arithmetic operation circuit. The integrated circuit includes a read bus for connecting the arithmetic operation circuit with a plurality of registers which store input data and/or output data of said arithmetic operation circuit. A precharge and sense circuit connects said arithmetic operation circuit to said read bus. The precharge and sense circuit includes a precharge circuit to precharge the read bus to a first level before the read operation, and a sense circuit to detect that the level of the read bus has discharged to a second, lower level after the read operation begins. In this way, the integrated circuit can detect very slight potential variations on said read bus.
