Charlie Andrews
Charlie was able to remember everything she read since she first manifested this power. She was also able to comprehend and use the knowledge gained almost immediately.

Charlie has the ability to remember everything that has happened in her entire life. She can memorize books word for word that she read in elementary school. She even remembers the night her parents died in a car crash when she was only six months old.

When her aneurysm started to burst, Charlie started to absently recite random information about a Japanese city.

Sixty-five years after being trapped back in 1944, Charlie was still able to remember what the weather was like when she was trapped there.

Sylar
Sylar was able to read the owner's manual for a tractor-trailer and immediately use that knowledge to drive the vehicle.

Matt Neuenberg
According to the testing the Company has done on him, Matt has the capability of remembering great amounts of information. With the aid of a goggle device, Matt is able to store an entire mainframe computer's worth of data and have his brain be a makeshift backup drive.
