Abstract
A content addressable memory (CAM) cell for a FLASH memory array includes four multiple-row columns of FLASH cells formed in a virtual ground architecture having a single diffusion between neighboring columns of cells. The first column has isolation elements therein and the third column has the same data value stored in each FLASH cell thereof. The CAM cell also includes elements for providing read and source voltages to the third column.
