A '''data crystal chip''', often referred to as a '''data crystal''',<ref>'''[[Halo: First Strike]]''', ''page 402'' (2010)</ref> a '''memory crystal''',<ref name="fs157">'''Halo: First Strike''', ''page 157'' (2010)</ref> or a '''data chip''',<ref>'''[[Halo: Glasslands]]''', ''page 211''</ref> is a [[human]] file storage and transfer device akin to 21st-century [[Wikipedia:USB flash drive|flash drives]]. Composed of silicon and crystal,<ref name="gl225">'''Halo: Glasslands''', ''page 225''</ref> a data chip can store immense amounts of data, such as the [[Riemann matrix]] of an [[artificial intelligence]]. Although most data chips are the size of a small [[Wikipedia:matchbook|matchbook]],<ref>'''[[Halo: The Cole Protocol]]''', ''page 265''</ref> some may be smaller than a thumb.<ref>'''Halo: The Cole Protocol''', ''page 13''</ref> A pea-sized data crystal chip variant is used to store [[Artificial intelligence#"Micro" AI|"micro" AI]]s, like [[Jerrod]]. They are compatible with a [[Portable computer|laptop]]'s auxiliary reader port and can connect to the laptop's [[holography|holographic]] projector.<ref>'''[[Halo: Ghosts of Onyx]]''', ''page 147''</ref>

==Background==
[[File:Mom, Son, & Daughter.png|thumb|250px|left|Doctor Catherine Halsey supplying [[John-117]] with [[Cortana]]'s data chip.]]
Data crystal chips are often used to store data that cannot be sent via wireless transmissions because of the data's sensitive or complex nature. They are used by the [[United Nations Space Command]] to store navigation and weapons data as well as strategic and tactical intelligence.<ref>'''[[Halo: Evolutions]]''', "[[The Mona Lisa]]", ''page 169''</ref> Data crystal chips are made up of a ceramic composite, with substrate filaments, conduit tracers, carbon sealant, silicon mesh, and crystal synthesis.<ref name="tfor as">'''[[Halo: The Fall of Reach - The Animated Series]]''', ''Act Two''</ref>

A relatively common storage medium for the [[Riemann matrix]] of an [[artificial intelligence]] construct—from [[Artificial intelligence#"Micro" AI|"micro" AIs]] to starship-grade [[Smart AI|"smart" AI]]s—a data crystal can be considered the physical entity of an AI.{{Ref/Reuse|gl225}} "Smart" AIs of high importance have a matrix fail-safe that will either destroy the data crystal or render it useless when activated.{{Ref/Reuse|fs157}} Despite this, [[Catherine Halsey|Doctor Catherine Halsey]]'s personal AI, [[Kalmiya]], was able to reconstruct a fragment of [[SPARTAN-III program|erased information]] from trace ionization that was taken from [[Araqiel]]'s data chip, after Halsey initiated his fail-safe.<ref>'''Halo: First Strike''', ''page 159'' (2010)</ref>

For the [[SPARTAN-II program]], by [[2525]], [[Materials Group]]'s [[Chi Ceti IV]] [[Damascus Materials Testing Facility|division]] was developing data crystal chips compatible with the [[MJOLNIR Powered Assault Armor]], given a budget of nearly three million [[credit]]s with materials imported from [[Muroto]].{{Ref/Reuse|tfor as}} With the [[MJOLNIR Powered Assault Armor/Mark V|Mark V]] and subsequent versions of the Mjolnir armor, a data crystal chip containing an AI matrix can be inserted into the [[SPARTAN programs|Spartan]] wearer's [[neural interface]]; this allows the AI and Spartan to synchronize on a mental level, fine-tuning the supersoldier's reflexes to an even greater degree.<ref>'''Halo: The Fall of Reach''', ''page 252'' (2001)</ref><ref>'''[[Halo: Combat Evolved]]''', campaign level, ''[[The Pillar of Autumn (Halo: Combat Evolved level)|The Pillar of Autumn]]''</ref> A data crystal chip may also be physically inserted into the systems of a [[Covenant]] [[Covenant fleet|fleet]] [[warship]]s or military [[space station]]s to allow the AI to infiltrate the ship's [[Covenant battle network|battle network]] and take control of the ship's systems.<ref>'''[[Halo: Mortal Dictata]]''', ''page 219''</ref><ref>'''Halo: First Strike''', ''page 77'' (2010)</ref> When a smart AI, [[Black-Box]], was inserted into the systems of ''[[Pious Inquisitor]]'', the AI instantly absorbed all the ship's information in the vessel's data banks and transferred it to his data chip.<ref>'''Halo: Mortal Dictata''', ''page 225''</ref> Data crystal chips can also be inserted into numerous terminals and consoles on [[Forerunner]] structures, including [[Installation 04]]<ref>'''Halo: Combat Evolved''', campaign level, ''[[Assault on the Control Room]]''</ref> and [[Requiem]].<ref>'''[[Halo 4]]''', campaign level ''[[Requiem (level)|Requiem]]''</ref> An [[armored matrix]] may be used to transport and protect an AI's data crystal chip; this is often done when no [[holotank]] is available.<ref>'''[[Halo: The Flood]]''', ''page 317'' (2003); ''page 354'' (2010)</ref>

==Trivia==
*Though [[Cortana]]'s data crystal chip is featured prominently in ''[[Halo: Combat Evolved]]'', ''[[Halo 3]]'', and ''[[Halo 4]]'', her method of transfer varies between each game. In ''Halo: Combat Evolved'', Cortana's matrix is transferred only when the chip is directly inserted into an access port. In ''Halo 2'', Cortana is capable of transferring from the MJOLNIR Mark VI's gauntlets to any electronic system in close proximity without using the chip. The chip returns in ''Halo 3'', though Cortana is seen transferring herself remotely to and from the device, much as she did via the suit's gauntlets in ''Halo 2''. ''Halo 4'' reintroduces the direct-insertion system from ''Halo: Combat Evolved'', despite Cortana having upgraded the suit since the events of ''Halo 3''. This may be due to Cortana's deteriorating state of rampancy, as at one point she mentions being "unable to move on her own".{{citation needed}}
*In ''[[Halo Infinite]]'', [[the Weapon]] first transfers into the chip by touching it in the same way that Cortana did in ''Halo 3'' before transferring into other systems by the Master Chief touching them as Cortana did in ''Halo 2'', albeit with the Master Chief first manifesting a hologram of her above his hand.

-Cortana displayed the ability to project a small hologram of herself from her data crystal chip{{Ref/Level|H4|[[Requiem (level)|Requiem]]}} and transfer herself into the chip just by touching it.{{Ref/Level|H3|[[Cortana (level)|Cortana]]}} She could also transfer herself into [[Installation 08]]'s systems by walking off of the chip and into the Control Room's terminal.{{Ref/Level|H3|[[Halo (Halo 3 level)|Halo]]}}
-When the Master Chief and [[the Weapon]] were paired together, the AI initially transferred herself from [[Installation 07]]'s systems into her data crystal chip by physically touching it like Cortana had earlier done while escaping from [[High Charity]].{{Ref/Level|Hi|Foundation}} However, the Weapon was subsequently able to transfer herself into systems by manifesting a hologram of herself over the left hand of the Master Chief's [[MJOLNIR Powered Assault Armor (GEN3)|GEN3]] armor and then walking off of it into a terminal. By touching her hologram, the Master Chief could then transfer the AI back into his armor without ever removing the data crystal chip.{{Ref/Game|Hi}}

-*The Master Chief appears to use multiple data crystal chips for Cortana in the series, particularly in ''[[Halo: First Strike]]''. When taking Cortana with him aboard ''[[Ascendant Justice]]'', it's mentioned that he downloads her into a data chip which is last seen inserted into a maintenance terminal aboard the vessel. Cortana later copies herself into another chip aboard the {{UNSCShip|Gettysburg}} which is subsequently left in the reactor subsystem aboard the ''[[Unyielding Hierophant]]'', meaning that he would've needed a new chip for Cortana by the time of ''[[Halo 2]]''.
