Abstract
A translation-lookaside buffer includes a content-addressable memory (CAM) cell to generate a CAM current signal with a first transistor configuration having a set of transistors of a predetermined size and connection. A reference current circuit generates a reference current signal with a second transistor configuration corresponding to the first transistor configuration, with the exception of the size and connection of selected transistors. A match sense amplifier selectively generates a match signal in response to the CAM current signal and the reference current signal.
