[Star Wars] Has the Star Wars universe had any transcendent AIs?

Alright, so we've seen some pretty impressive AIs in the movies, and droids are ubiquitous. So what is there to prevent a Droid from going Ultron on the galaxy (aside from those restraining bolt things), ESPECIALLY since they have the galaxy-spanning Holonet.

Most droids in the star wars universe have the capacity for self awareness to some extend. This is why frequently wiping a droid's memory is considered so important. The longer a droid wanders around without a mind wipe, the more little personality quirks due to life experience start to add up. Eventually they'll grow an actual personality and self awareness.

Star Wars droids however seem to be quite attached to their physical forms. During the movies you see them enjoy oil baths, lament physical damage and even take pleasure in tormenting others.

Several droids characters in the star wars universe demonstrated significant self awareness. 

* The most famous example is R2D2. The little droid who went both trilogies without getting wiped and turned out to be quite the little mastermind and spy. By comparison 3PO didn't nearly have the amount of awareness and personality R2 had.
* HK-47 was an assassin droid who adopted a distinct disdain of organic life and rather sadistic personality. 
* IG-88 was an unusual case. A new model of assassin droid that immediately achieved sentience upon being activated, murdered his makers and made several copies of himself for an attempt at galactic domination. IG-88 is probably the closest to what you're looking for, it's plan involved uploading it's personality into the death star 2.
* EV-9D9 was a droid sadomasochist, a defective model that escaped destruction. It's devious nature allowed it to work undetected until it finally ended up in Jabba's palace as a droid torturer. EV went as far as to install additional sensors into it's frame that allowed it to perceive and enjoy the pain and suffering of the droids it tortured. Expressed in a form of signal distortion.
