INTERNAL VOLTAGE GENERATION CIRCUIT

摘要

PURPOSE: An internal voltage generating circuit is provided to prevent a current loss by preventing an internal voltage from being simultaneously driven and discharged. CONSTITUTION: An internal voltage driving unit(21) generates an inverted enable signal by buffering an active signal and generates an inverted driving signal enabled if an internal voltage is higher than a target level. An internal voltage discharge unit(22) discharges charges of a power line in response to the inverted enable signal and the inverted driving signal. A first buffer unit generates the enable signal and the inverted enable signal by buffering an active signal. A comparison unit is driven in response to the enable signal and generates a driving signal by comparing a distribution voltage with a reference voltage. A second buffer unit generates the inverted driving signal and a pull-up signal by buffering the driving signal.
