Title: Internal power supply voltage generating circuit in semiconductor memory device
Inventor: HWANG HYONG RYOL
IPC: G11C5/14
Filed: 2006-02-22
Abstract: An internal power supply voltage generating circuit of a semiconductor memory device is provided to increase power-up slope even after a power-up signal is set up. An operation control signal generation part selects a first input when setup transition of a power-up signal is generated and selects a second input when an active command signal is applied, and provides the first input and the second input to an output stage as an operation control signal. An internal power supply voltage generator(10,11) continues to increase the internal power supply voltage so that the output level of the internal power supply voltage follows a reference voltage when the operation control signal is provided by the setup transition of the power-up signal, and stops increasing the internal power supply voltage when the operation control signal is provided by the active command signal.
