Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2002042471
Kind Code:
A
Abstract:
To provide a semiconductor device which can realize reduction of the layout area and the testing time for voltage adjustment and generates internal voltages.
A constant voltage generating circuit (2) is provided to commonly generate a constant voltage (Vref0) for reference voltages (Vref1-Vrefn) corresponding to plural internal voltages. Plural reference voltages are generated from the common constant voltage.
