It is discovered that the molecular packing and the orientation of crystallite arrangement in the film state are critical to the performance of the typical sandwich organic‐based memory devices (OMDs). Here, a solvent‐vapor annealing (SVA) strategy is firstly developed for amphipathic molecules to regulate the film morphology and intermolecular stacking, so as to obtain the satisfied performance. Through the screening of SVA solvents, an evidently upgraded nonvolatile memory behavior based on MeOH‐annealed film with superior reproducibility, a low switching voltage of −2.3 V and high ON/OFF ratio of 10 4 are observed. This work not only gives a fresh application of the amphipathic materials to OMDs, but really provides a general guiding significance for SVA solvent selection to achieve controllable crystallite orientation and effective OMDs performance.
