Abstract:
A semiconductor integrated circuit comprising:a first voltage node of a first voltage level;a second voltage node of a second voltage level;a first data store circuit, coupled to said first and second voltage nodes, which stores a data;a second data store circuit;a control circuit which outputs a transfer signal and a switching signal;a data transfer circuit, coupled between said first data store circuit and said second data store circuit, which selectively transfers the data in said first data store circuit to said second data store circuit in response to the transfer signal;a first conductive line which supplies said first voltage level to said second data store circuit;a second conductive line which supplies said second voltage level to said second data store circuit;a first switch circuit, coupled between said second voltage node and said second conductive line, which selectively connects said second voltage node to said second conductive line in response to the switching signal; anda first resistive element coupled between said second conductive line and said first voltage node, so that a voltage level of said second conductive line gradually changes from said second voltage level toward said first voltage level after said second conductive line is disconnected from said second voltage node by said first switch circuit.
