Munkhshur Narmandakh
Mongolia
Set by Mongolian memory champion Munkhshur Narmandakh at the 2023 World Memory Championships. He accurately memorized 3,240 randomly sequenced digits in one hour. Number memorization is the most fundamental yet intensely demanding discipline in memory sports, with most competitors employing the Memory Palace (method of loci) technique. This record stands as a defining example of the upper limits of human short-term memory capacity.
