Abstract:
In a semiconductor device having a first power supply voltage, a circuit for generating stabilized configuration upon power-up, comprising:a first data store for storing configuration information, the first data store receiving a power-on reset signal and providing the configuration information as data;a mock fuse bit for receiving for receiving the power-on resist signal, tracking response of the first data store, and generating a fuse configuration reset signal;a configuration signal generator for receiving the fuse configuration reset signal and generating a configuration reset signal in response thereto, the configuration reset signal being delayed with respect to the power-on reset signal, the configuration signal generator includes a charge device coupled between a node and a predetermined voltage for maintaining the node at the predetermined voltage as the first power supply voltage increases in magnitude during power-up; anda second data store for receiving the configuration reset signal from the configuration signal generator and storing the data from the first data store.
