Datavore

A datavore was a creature with the ability to ingest information like food, essentially feeding on knowledge.

The Seventh Doctor speculated that the Process was a datavore when, in its attack on his ship, it ate the TARDIS manual and left other books unharmed. It also later fed on the mental energy of the Time Scaphe crew. (PROSE: Cat's Cradle: Time's Crucible)

AM!xitsa, a drone and member of the People, had an internal datavore trap where it had discarded 6,547 unpublished theses. When Kadiatu Lethbridge-Stewart attacked AM!xitsa and it struck a tree, the datavore regurgitated all theses. (PROSE: The Also People)

Krllxk was a datavore, but inorganic and artificially created. (PROSE: Time of Your Life)
