Abstract
There is disclosed a code addressable memory (“CAM”) cell in a flash memory device. In order to stabilize the operation of the CAM cell in a flash memory device operating at a low voltage, the present invention manufactures a CAM cell in which a floating gate is formed to extend on more than two active regions and more than two cell arrays are connected in parallel commonly using a source region and a drain region. Therefore, the present invention can increase the gate-coupling ration of the CAM cell, thus stabilizing the operation of the CAM cell at a device for low-voltage use.
