Abstract
A ternary content addressable memory (TCAM) has at least one TCAM cell comprising first and second memory bitcells for storing first and second bit values representing a cell state comprising one of a first cell state, a second cell state and a mask cell state. The first and second memory bitcells share a pair of bitlines for accessing the first and second bit values. Access control circuitry is provided for triggering, in response to a clock signal, a read or write access to the first memory bitcell during a first portion of a clock cycle and triggering a read access or write access to the second read bitcell during a second portion of the clock cycle.
