Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2011003175
Kind Code:
A
Abstract:
To provide a semiconductor device capable of generating an internal voltage having a voltage level corresponding to the voltage level of an externally supplied power voltage.
The semiconductor device includes: a voltage level detector (31) for detecting the voltage level of the externally supplied power voltage (VDD); and an internal voltage generator (reference voltage generator 35, level shifter 32, selector 33 and voltage driver 34) for generating the internal voltage (VREFi) having the voltage level corresponding to a detection result (VDD_DET_O) of the voltage level detector.
