PURPOSE: An integrated distance measuring device of an EEPROM(Electrically Erasable Programmable Read-Only Memory) address mapping type with improved security and credibility is provided to extend a life time by evenly distributing physical impact applied to a memory and to rapidly record. CONSTITUTION: An integrated distance measuring device comprises a speed signal input unit, a control unit, an integrated distance storing unit, and a display unit. The speed signal input unit obtains a driving speed from the number of rotation of a rotary shaft. The control unit calculates a section driving distance and total driving distance from the speed signal input unit. The integrated distance storing unit stores calculation information of the control unit. The display unit displays the section driving distance and total driving distance calculated from the control unit. The control unit assigns a plurality of memory addresses of the integrated distance storing unit and appoints a recording order and performs a recording process while circulating all addresses assigned per each 1km increase.
