Data buffer circuit structure, layout structure of multiple data buffer circuits, and memory

A data buffer circuit structure, comprising:

• a first amplification circuit, a second amplification circuit, a decision equalizer, and a power module, an output terminal of the first amplification circuit, an input terminal of the second amplification circuit, and adjustment output terminals of the decision equalizer being connected through a signal line, and the first amplification circuit, the second amplification circuit, the decision equalizer, and the power module being arranged in a same direction,
• the power module comprising a first power supply unit and a second power supply unit, the first power supply unit being configured to supply power to the first amplification circuit and the decision equalizer, and the second power supply unit being configured to supply power to the second amplification circuit;
• and
• a minimum distance between the first power supply unit and the first amplification circuit being less than a minimum distance between the first power supply unit and the second amplification circuit, and a minimum distance between the second power supply unit and the second amplification circuit being less than a minimum distance between the second power supply unit and the first amplification circuit.
