Direct-current voltage generating circuit intermittently activated for reducing electric power consumption |
摘要 |
Disclosed is a DC voltage generating circuit for reducing an electric power consumption in a semiconductor memory device. The DC voltage generating circuit comprises: a refresh counter for setting a refresh cycle; a power source supply controller for logically combining a counting value supplied from the refresh counter and a self-refresh timer driving signal, thereby to generate a power source supply control signal in a refresh section; and a DC voltage generator for generating and supplying a DC voltage through an output terminal of the DC voltage generator, as controlled by the power source supply control signal supplied from the power source supply controller.
