Origami has recently received significant interest from the scientific community as a method for designing building blocks to construct metamaterials. However, primary focus been placed on their kinematic applications by leveraging compactness and auxeticity of planar origami platforms. Here, we present volumetric cells-specifically triangulated cylindrical (TCO)-with tunable stability stiffness, demonstrate feasibility non-volatile mechanical memory storage devices. We show that pair TCO cells can develop double-well potential store bit information. What makes this origami-based approach more appealing is realization two-bit memory, in which two pairs are interconnected one acts control other pair. By assembling TCO-based truss structures, experimentally verify nature units operation purely one- prototypes.Origami popular design authors assemble structure, predict its axial rotational movements during folding, storage.
