Abstract:
1. An internal voltage generation circuit for use in a semiconductor device, comprising: a standby internal voltage generator which is to be driven during a standby operation and an active operation, and supplies a voltage to an internal voltage end; a first active internal voltage generator for supplying a voltage to the internal voltage end in response to an active signal being activated during the active operation; and a second active internal voltage generator which is to be driven only for a predetermined time period in response to the active signal, and supplies a voltage to the internal voltage end, wherein the second active internal voltage generator includes: an active signal sensing circuit for sensing the active signal; and an internal voltage generator for generating a voltage in response to an output signal of the active signal sensing circuit, wherein the active signal sensing circuit is provided with a pulse generator for generating a pulse signal which becomes active only for the predetermined time period after receiving the active signal, wherein the pulse generator includes: a delay circuit for taking and delaying the active signal; and an output circuit for receiving the active signal and an output signal of the delay circuit to provide the pulse signal.
