ABSTRACT:
A level convertor is provided between circuits, which act with different power supply voltages, respectively, and converts a first voltage level of an output of a circuit to a second voltage level, which corresponds to an operational voltage level of another circuit. The level convertor comprises a level shift circuit, which receives the first voltage level and outputs an output of the second voltage level, and a buffer circuit, which receives the output of the second level and a control signal, and fixes the output of the second voltage level to a low logic level, when the control signal is a low logic level. The control signal may be used to set a timing for registering the data to a register, avoiding data in an instable state when power is supplied, from being registered to the register.
