| 摘要 |
A storage circuit comprises a first clock receiver circuit for receiving an external clock signal so as to produce from said external clock signal a first internal clock signal and so as to output the first internal clock signal for use within the storage circuit, as well as a second clock receiver circuit for receiving said external clock signal and for producing from said external clock signal a second internal clock signal, said second clock receiver circuit consuming less current than said first clock receiver circuit. In addition, a circuit block is provided, which operates on the basis of said first or second internal clock signal and which is used for switching off said first clock receiver circuit when a power-down-precharge mode exists, said circuit block operating on the basis of said second internal clock signal, when the first clock receiver circuit has been switched off. A reduced current consumption can be achieved by the present invention in this way.
