ElectriBrain
From The Monoverse: A Non-Linear Sci-Fi Epic
ElectriBrain is a self-proclaimed "brain on a chip" that allows a user to insert a chip and reference any of the material on said memory chip as long as it is inserted and working. It can also be referenced to as a "second brain."
The ElectriBrain is not widely used as it requires surgery. It also has a stigma around it because it makes you more like a cyborg than a natural human.
The ElectriBrain technology is for the explicit use in natural humans, as opposed to cyborgs, whom already have such capabilities built-in.
