    摘要: 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.

    摘要: 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.
