Abstract
A mixed-voltage interface transfers signals serially between a pair of circuit blocks operating at different voltage levels in a semiconductor integrated circuit. Control, address, and data signals are multiplexed onto a common signal line. The number of necessary signal lines is thereby greatly reduced, as compared with parallel signal transfer, and a separate electrostatic discharge protection circuit can be provided for each signal line without the need to devote excessive space to protection circuitry.
