I've never encountered this before, so I hope you don't mind me asking some questions. 1) What constitutes a "digital memory"? I can imagine images, videos, notes, etc. that you've taken, but I don't know if that's all that you mean. (Google saving your location history is "memory" but maybe not "yours".) 2) What does it mean to you that they're "stored perfectly"? Is that just that they're stored at all or are you suggesting some rigor to their storage security such that they can't be modified easily by someone other than you?
