Abstract
Apparatuses and methods for providing an indicator of operational readiness of various circuits of a semiconductor device following power up are described in the present disclosure. An example apparatus includes a first circuit configured to receive a supply voltage and further configured to provide an active first signal responsive to the supply voltage exceeding a threshold voltage. The example apparatus further includes a second circuit coupled to the first circuit and activated by the active first signal, the second circuit configured to provide an active second signal when a third circuit is ready for operation.
