Classification: H03K

Abstract:
A semiconductor integrated circuit device including a precharge circuit comprising:a first charge circuit for charging a node to a predetermined potential;a second charge circuit for charging the node to the predetermined potential, the second charge circuit being higher in charging speed than the first charge circuit;a charged level detect circuit for detecting a charged level of the node and driving the second charge circuit when the first charge circuit charges the node to a predetermined charged level lower than the predetermined potential;a charged level stabilization circuit for outputting a substantially fixed potential when the charged level of the node is over the predetermined charged level lower than the predetermined potential; anda charged level control circuit for expediting activation of the second charge circuit, the charged level control circuit being coupled to the second charge circuit and expediting the activation of the second charge circuit when the first charge circuit charges the node to the predetermined charged level.
