SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/156711
Kind Code:
A1
Abstract:
[Problem] To quickly start an internal voltage generating circuit after a control signal has been made active.
[Solution] A semiconductor device comprises a comparator circuit (CP) that compares a reference voltage (VREFD) and an internal voltage (VPERD) during an activation period of a start signal (INIT) and controls the electric potential level of a gate potential (GN) in accordance with the comparison results, a transistor (N3) that receives the gate potential (GN) at a gate electrode and outputs the internal voltage (VPERD), and a transistor (P3) that puts the transistor (N3) into a conducting state regardless of the results of the comparison by the comparator circuit (CP) during a fixed period from when the start signal (INIT) is made active. By virtue of the present invention, the internal voltage generating circuit can quickly start because the transistor (N3) is forcibly placed into a conducting state during the fixed period from when the start signal (INIT) is made active.
