I dont see any memory mode. it starts where you left off plus the next level. I wish you could pick where it always starts. As another reviewer states, not the best for medical use as it does not reset to lowest automatically and you cant pick where to start. it just cycles through the three settings which is annoying. I feel sorry for my patients that accidentally get blasted with the full brightness, my bad. Good color rendition, attractive, appears durable. My son loves playing with it, so it makes a great kid gift also. i might look for a better option for medical use.
