Repository of knowledge

"All the knowledge of the Ancients." "That's a lot."

- Daniel Jackson and Vala Mal Doran

The Ancients' repository of knowledge is a device created by the Ancients to hold massive amounts of information.

Overview
The Repository of Knowledge is a library that downloads the entire knowledge bank of the Ancients into the brain of a person. This knowledge is, however, far too vast for a human brain to fully comprehend, so much so that the mind of the person exposed to the amount of data within will slowly degrade after being exposed.

Thousands of years ago, the Asgard managed to download only a small amount of the information within the Repository to their own computers, but they only scratched the surface of what was contained within. Thor has speculated that the amount of knowledge contained in the Repository is so great that it might be infinite.

On two occassions, Jack O'Neill was able to use it, after recieving incredible amounts of information from the Repository, but he never retained any of the knowledge, because both times the Asgard cleared his mind.

Merlin also used the Repository, in conjunction with a molecular construction device to create the Sangraal, and then to transfer his memories to Daniel Jackson. Jackson stated that Merlin's device allowed one to visualize a program and machine, and then make modifications to it.
