Patent ID: 8817055

Claim:
A data transfer circuit comprising: a first latch section that latches an input data inputted to said first latch section, and outputs a single-phase first latch result obtained by latching said input data; and a second latch section that latches said single-phase first latch result outputted from said first latch section, wherein said first latch section includes a first inverter and a second inverter, an input from said first inverter being inputted to said second inverter via a switching circuit, wherein a first power supply voltage of said first latch section is set to a first voltage or a second voltage that is different from said first voltage, and a second power supply voltage of said second latch section is set to said second voltage, wherein said first power supply voltage of said first latch section is set to said first voltage when the input data inputted and latched in the first latch section, and set to said second voltage while said single-phase first latch result is transferred to said second latch section, and wherein said single phase first latch result is an inverted output of the first latch result.
