Abstract
A semiconductor integrated circuit comprising: a first voltage generator configured to generate a first voltage in response to activation of a first enable signal, wherein the first enable signal is generated by detecting a level of the first voltage; and a second voltage generator configured to generate a second voltage in response to activation of at least one of the first enable signal and a second enable signal, wherein the second enable signal is generated by detecting a level of the second voltage.
Claims7
A semiconductor integrated circuit comprising:
- a first voltage generator configured to generate a first voltage in response to activation of a first enable signal, wherein the first enable signal is generated by detecting a level of the first voltage;
- a pulse generator configured to generate a pulse signal synchronized with the first enable signal;
- a second voltage generator configured to generate a second voltage in response to activation of at least one of the pulse signal and a second enable signal, wherein the second enable signal generated by detecting a level of the second voltage;
- and
- voltage generator configured to generate the second voltage in response to the pulse signal;
- wherein output terminals of the second voltage generator and the voltage generator are connected to a same node.
A method of controlling internal voltages of a semiconductor integrated circuit comprising;
- pumping of a second voltage is performed when at least one of a first enable signal and a second enable signal is activated, or when a pulse signal is activated,
- wherein the first enable signal is activated when a first voltage reaches a first value, the second enable signal is activated when the second voltage reaches a second value, and the pulse signal is activated when the first enable signal is activated, and the pulse signal is inactivated before the first enable signal is inactivated.
