Semiconductor memory power control system with voltage generator to supply voltage to an internal circuit by boosting an external voltage

摘要

A semiconductor device is provides which includes: a first boost circuit that generates a first boost voltage by boosting an external voltage and supplies the first boost voltage to an internal circuit; and a first circuit that supplies the external voltage to an output of the first boost circuit when power is turned on and supplies the first boost voltage to the output of the first boost circuit when the external voltage reaches a given voltage.
