The Memory Banks is a location in Bowser's body, as seen in Mario & Luigi: Bowser's Inside Story. It is in Bowser's brain (possibly the temporal lobe) and is responsible for storing all of Bowser's memories. The Memory Banks is personified as a organized computer database in form of a library, with each memory stored as a separate file on shelves and is analogous to memory stored on a computer's hard disk. It is protected by a pixelated Napse known as the Librarian that works to organize and back up the memories and also to fight off intruders.
When Bowser cannot recall the combination to a safe that contains a Star Cure in Bowser's Castle, he politely (though reluctantly) asks Chippy to help out. So, Mario, Luigi, and Starlow travel into the Memory Banks and find the Librarian, who briefly scans and determines the trio to be viruses. It transforms into Bowser Memory ML and engages in battle.
After being defeated, the Librarian transforms into Memory Peach (whom it claims as Bowser's most carefully preserved memory) and decides to cooperate. She states that the memory containing the combination to the safe was damaged after Bowser was smashed against a boulder by the Fawful Express. Retrieving the scrambled memory from the archives, the brothers work to repair the memory and restore the combination. Bowser is then able to open the safe and grab the Star Cure.
