The '''Riemann cycling-thought matrix''' is a central component in [[United Nations Space Command|UNSC]] [[artificial intelligence]] constructs. It contains a code directory, where all the impulses in an AI's mind exist; as such, it is effectively an AI's "brain". The matrix is not a physical object itself; rather it is a program, allowing the AI to be stored in various forms of hardware, including a data center's [[nano-assemblage]]<ref>'''[[Halo: Contact Harvest]]''', ''page 182''</ref> or a [[data crystal chip]] for mobility.

==Fail-safe==
Some AIs have personal fail-safes. [[Catherine Halsey|Dr. Halsey]] stated that not all AI have such a fail safe, rather, only the important ones.<ref name="erase">'''Halo: First Strike''', ''page 135''</ref> In case of [[rampancy]] or other danger to [[human]]s caused by the AI, the fail safe can be activated. It works by generating a pulse beam of high frequency ultraviolet light in the Riemann matrix, destroying the higher thought functions of the AI, effectively erasing it. It is unknown how common this information is since [[James Ackerson]]'s AI [[Araqiel]] failed to recognize the fail safe. This indicates that the information is kept secret from the AIs for obvious reasons.<ref>'''Halo: First Strike''', ''page 128''</ref>

The matrix fail-safe was used by [[Catherine Halsey|Dr. Halsey]] to shut down both Araqiel and [[Kalmiya]].<ref name="erase"/>

==Method of function==
Because [[Smart AI|"smart" AIs]] are essentially copied human minds, the Riemann matrix is likely to be a software model of the human brain, similar to real-life proposals to create AI. The information stored in the matrix is, in essence, models of what happens inside human neurons. Each piece of the matrix is connected with others, allowing currents similar to those inside a human brain.

The matrix's name is probably a result of a non-linear nature (Riemann was a 19th century mathematician who made several breakthroughs in non-linear geometry.<ref>[[Wikipedia: Bernhard Riemann]]</ref>)

A [[Forerunner]] [[Durance]], used to contain the [[essence]] of a [[Composer|composed]] individual, was noted by Dr. Halsey as exhibiting remarkable similarities to a UNSC AI matrix.<ref>'''[[Spartan Ops]]''' — ''[[Memento Mori|S1E5 Memento Mori]]''</ref>
