Positronic decompiler
A positronic decompiler was a program that broke down the source code of the matrix in the positronic brain of a Soong-type android, allowing the existing code to be altered, essentially changing the behavior and abilities of the android. 

Data's positronic decompiler featured a "type R" phase discriminator, while his brother Lore had a "type L". ()
