Abstract
In a method and system for providing a CAM (content addressable memory) cell of a flash memory device, a respective core flash memory cell to be used as the CAM cell is fabricated as part of a core array of the flash memory device. In addition, the respective core flash memory cell is accessed from the core array as the CAM cell for a CAM function within the flash memory device. Components used for supporting operation of the core array are also used for accessing the core flash memory cells of the additional sector for such CAM functionality. Thus, CAM functionality is provided with a minimized number of components and with minimized area of the die of the flash memory device. In addition, because the CAM cells are implemented as core flash memory cells of the core array, the CAM cells may reliably undergo more numerous programming and erasing cycles.
