Abstract
Embodiments of the present invention include an interface circuit to put an integrated circuit into a test mode and a decoder to decode one or more commands provided to the integrated circuit. The decoder includes sub-circuits, and each sub-circuit has a number of transistors coupled in series. The transistors coupled in series have control gates coupled to a clock signal or one of several inverted or non-inverted command signals representing a command. The control gates in each sub-circuit are coupled such that a unique pattern of the clock signal and the command signals will switch on all of the transistors to decode the command. Each sub-circuit is capable of decoding a single command. The sub-circuits have ratioed logic with more n-channel transistors than p-channel transistors. The decoder may be fabricated with a flexible placement of vias.
