Absolute memory

Absolute memory is the ability to remember absolutely everything one thinks, feels, encounters, and experiences. People with an absolute memory can remember and recall everything that they have ever experienced, encountered or learned in their lifetime. They only need to read, hear or see something once and they will never forget it. They continue to learn for the rest of their lives and their brain will simply compress neural synapses to contain it all, allowing memory of every event, experience or bit of knowledge from birth to the present. Their mind is also entirely immune to Memory Manipulation, unless the ability is first negated or stolen.
