    Abstract: Methods for erasing an integrated circuit memory device having a cell array region that includes a main cell array region, a first dummy cell array region on a first side of the main cell array region and a second dummy cell array region on a second side of the main cell array region are provided. A first erasure voltage is applied to a plurality of main control gate electrodes in the main cell array region. The plurality of main control gate electrodes include a first outermost main control gate electrode adjacent to the first dummy cell array region and a second outermost main control gate electrode adjacent to the second dummy cell array region. A second erasure voltage is applied to an integrated circuit substrate in the main cell array region. The second erasure voltage is greater than the first erasure voltage. A third erasure voltage is applied to a first inner dummy control gate electrode adjacent to the first outermost main control gate electrode and a second inner dummy control gate electrode adjacent to the second outermost main control gate electrode. The third erasure voltage is less than the second erasure voltage. Related devices are also provided.

    Abstract: A floating trap type non-volatile memory device and fabrication method thereof are provided. The floating trap type device comprises a substrate, a gate electrode formed on the substrate. A charge storage layer is interposed between the substrate and the gate electrode. A tunneling layer is interposed between the substrate and charge storage layer. The charge storage layer comprises a material having a narrower band gap than silicon nitride. The charge storage layer preferably formed of tetrahedral amorphous carbon. The potential barrier between the charge storage layer and the tunneling layer is increased by using the tetrahedral amorphous carbon as the charge storage layer. Therefore, the charge retention characteristic of the floating trap type device is improved.
