Abstract
A semiconductor apparatus comprises a power-up signal generation section configured to generate a power-up signal, a driver configured to drive and output the power-up signal, and a main circuit block configured to perform predetermined functions in response to an output from the driver, wherein the power-up signal generation section and an input terminal of the driver are connected by a disconnectable element.
Claims2
A semiconductor apparatus comprising:
- a master chip configured to generate a first power-up signal and inactivate the first power-up signal in response to a plurality of detection signals;
- a plurality of slave chips configured to respectively generate second power-up signals and respectively generate the plurality of detection signals by respectively detecting deactivations of the second power-up signals,
- a first signal transmission element connected in common between the master chip and the plurality of slave chips and supply the first power-up signal to the plurality of slave chips;
- and
- a second signal transmission element connected in common between the master chip and the plurality of slave chips and supply the detection signals to the master chip as a single signal.
