Abstract
A semiconductor apparatus includes a data input and output (input/output) circuit configured to operate by receiving a first voltage, a core circuit configured operate by receiving a second voltage, and a control circuit configured to output a power control signal for activating the data input/output circuit when the first voltage is higher than a first set voltage and the second voltage is higher a second set voltage.
Claims20
A semiconductor system comprising:
- a power voltage controller including one or more first type transistors, configured to generate a power control signal by detecting levels of an input voltage;
- and
- a level shifter including one or more second type transistors, configured to receive the power control signal as a power voltage,
- wherein at least one internal voltage of the one or more second type transistors is lower than an internal voltage of at least one of the one or more first type transistors.
