SSI stands for small-scale integration. It is a historic classification for integrated circuits that contain fewer than 10 to 100 transistors, typically implementing basic logic functions like a few logic gates or a single flip-flop. These components formed the building blocks of early computers before higher density manufacturing became possible.
We had to reverse engineer an old flight controller built entirely out of 7400-series SSI logic chips.
