Dynamic d flip-flop, data operation unit, chip, hash board and computing device

A dynamic D flip-flop, comprising:

• an input terminal for inputting a first data;
• an output terminal for outputting a second data;
• a clock signal terminal for supplying a clock signal;
• a first latch unit for transmitting a data at the input terminal and latching the first data under control of the clock signal;
• a second latch unit for latching the data transmitted by the first latch unit;
• and
• an output drive unit for outputting the data received from the second latch unit;
• the first latch unit, the second latch unit, and the output drive unit are sequentially connected in series between the input terminal and the output terminal;
• and
• a first node is provided between the first latch unit and the second latch unit, and a second node is provided between the second latch unit and the output drive unit;
• wherein, further comprising a data retention unit electrically connected to the first node and/or the second node, the data retention unit is configured for assisting in storing the data latched at the first node and/or the second node.
