There are in fact booklets which you can read while you pray the Rosary (to better meditate on the mysteries). Look for Scriptural Rosary booklets. Here’s a good website that has passages to meditate on (look for the first image on the webpage ): mgrfoundation.org/Rosary.html
If you haven’t yet heard of St. Louis de Montfort’s the Secret of the Rosary, I suggest you read it (one of the best reads I’ve ever had the privilege to enjoy ). It will help you better understand the Rosary, thereby (in theory) helping you remember it better.
