Abstract
Systems and methods provide new circuits that increase aCAM precision by leveraging the concept of range segmenting to representationally store an analog voltage range across multiple aCAM cells/sub-circuits (here the representationally stored analog voltage range may correspond to a word entry). In this way, a circuit of the presently disclosed technology can increase precision (e.g., the number of programmable levels that can be used to store a word entry and/or the number of programmable levels that an input signal can be search against) linearly with each aCAM cell/sub-circuit added to the circuit. Accordingly, circuits of the presently disclosed technology can be used to carry out more complex computations than conventional aCAMs—and thus can be used in a wider range of computational applications.
