PURPOSE: A data storage circuit to maintain a state in a precharge process is provided to form a firm latching device with a differential data input and a reduced phase limit. CONSTITUTION: An input stage includes an input latching element(10) and a dual data line to output a data value and an inverted data value to an output stage. The input latching element outputs the data value by outputting a logic value of 1 to the dual data lines and discharging one of the dual data lines to 0. The output stage depends on the data value received from the dual data line and has a preset value. The output stage includes an output latching element(20) to maintain the preset value, two switching devices to update the output latching element, and an output unit.
