    Abstract: A field emission display apparatus including a field emission display panel and a driving device for the field emission display panel. The driving device includes a power supply unit, the power supply unit including an abnormal current detection unit and a discharge circuit. The abnormal current detection unit generates an arc-current detection signal when the value of a current flowing between a negative anode voltage terminal of the field emission display panel and a common ground line is larger than an upper limit. The discharge circuit generates a short circuit between an anode plate of the field emission display panel and the negative anode voltage terminal when the arc-current detection signal is generated from the abnormal current detection unit.

    Abstract: A memory system includes a flash memory device and an interface device. The flash memory device includes a one-time programmable block where protection data information is stored in a predetermined region, and the interface device includes a register for storing one-time programmable lock status information to indicate whether the one-time programmable block is programmed. When a program/erase command is applied externally in a one-time programmable mode, the interface device having the one-time programmable lock status information indicates whether the one-time programmable block is programmed. If the one-time programmable lock status information indicates that the one-time programmable block is programmed, the interface device cuts off an external access to the one-time programmable block.

    Abstract: A non-volatile memory device comprises a memory cell array having a plurality of non-volatile memory cells arranged in rows and columns. Selected memory cells are programmed by applying program voltages thereto. Next, data bits stored in the selected cells are read. Then, a first column scan operation is performed to determine whether any of the selected memory cells is inadequately programmed. Upon determining that at least one of the selected memory cells is inadequately programmed, a second column scan operation is performed to detect a total number of the selected memory cells that are inadequately programmed. Upon determining that the total number of the selected memory cells that are inadequately programmed is less than a number that can be corrected by an error correcting circuit, the program operation terminates with a program pass status.

    Abstract: Provided is a method for driving an electron emission device that reduces the required withstand voltage of an integrated circuit constituting a scan driver, which reduces both the manufacturing costs of an electron emission device and the likelihood of noise in the scan driver, as well as preventing back emission. Scan signals are applied to scan electrode lines during a scan period and an offset period, which is a non-scan period. Display data signals are applied to data electrode lines during a first data period, when a difference between a voltage of the display data signal and a voltage of the scan signal is greater than or equal to an emission start voltage; and during a second data period, when the voltage difference is less than the emission start voltage.
