Abstract
In one form of the invention, circuitry having exclusive-OR and latch functionality includes timing circuitry and logic circuitry. The circuitry includes a memory, with first and second memory nodes, for storing a state and its complement, and first and second timing circuitry portions, each operable to receive at least one timing signal, coupled to the respective memory nodes. The logic circuitry includes first and second logic circuitry portions, each of which is operable to receive at least first and second data signals. Each of the logic circuitry portions is coupled in series with a conditionally conductive path of one of the respective first and second timing circuitry portions.
