Abstract
A circuit for searching a content addressable memory includes a driver which generates a plurality of search line values, different combinations of which are used to implement a one-hot encoding scheme for searching the memory. Two or more cells in the memory may be consecutive bit positions of a word, and the driver may be synchronously operated to generate the different combinations of values.
