A semiconductor structure includes: a base substrate; an insulator, located on one side of the base substrate; bit lines, arranged in the insulator, the bit lines being distributed at intervals along first direction and extending along second direction; active bodies, located in the insulator, the active bodies being located on sides of respective bit lines facing away from the base substrate, orthographic projection of each active body on the base substrate at least partially coinciding with the orthographic projection of a respective bit line on the base substrate, and the active bodies being distributed at intervals along second direction; and word lines, located in the insulator and located on sides of respective bit lines facing away from the base substrate, the word lines being distributed at intervals along second direction and extending along first direction, and only one word line being arranged between two adjacent active bodies in second direction.
