    • 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.
    • 存储器系统包括闪存器件和接口器件。 闪存装置包括保护数据信息存储在预定区域中的一次性可编程块,并且接口装置包括用于存储一次性可编程锁定状态信息的寄存器,以指示一次性可编程块是否被编程。 当在一次性可编程模式中外部应用编程/擦除命令时,具有一次性可编程锁定状态信息的接口装置指示一次性可编程块是否被编程。 如果一次性可编程锁定状态信息指示一次性可编程块被编程,则接口设备切断对一次性可编程块的外部访问。

    • 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.
    • 非易失性存储器件包括具有以行和列排列的多个非易失性存储单元的存储单元阵列。 所选存储单元通过向其施加编程电压而被编程。 接下来,读取存储在所选择的单元中的数据位。 然后,执行第一列扫描操作以确定所选择的存储单元中的任何一个是否未被编程。 在确定所选择的存储器单元中的至少一个存储器单元不充分地被编程时,执行第二列扫描操作以检测未编程的所选存储器单元的总数。 在确定编程不正确的所选存储器单元的总数小于可由纠错电路校正的数量时,程序操作以程序通过状态终止。

    • An electron emission display and a method of controlling the same, in which a voltage applied between a cathode electrode and a gate electrode is adjusted according to an image level, includes: a pixel portion having a plurality of electron emission devices formed adjacent to a region where a plurality of data lines intersects a plurality of scan lines; a data driver supplying a data signal corresponding to video data to the plurality of data lines; a scan driver supplying scan signals to the plurality of scan lines in sequence; a power supply supplying power to the data driver and the scan driver; and a voltage level controller controlling a voltage difference between an cathode electrode and a gate electrode of the electron emission device on the basis of an image level corresponding to the video data. With this configuration, a contrast of an image is high in the case of a low image level and a power consumption is limited in the case of a high image level, and an electron emission device is prevented from deterioration.
    • 根据图像级别调整施加在阴极电极和栅电极之间的电压的电子发射显示器及其控制方法,包括:具有与区域相邻形成的多个电子发射器件的像素部分 其中多条数据线与多条扫描线相交; 数据驱动器,将对应于视频数据的数据信号提供给所述多条数据线; 扫描驱动器依次向所述多条扫描线提供扫描信号; 向数据驱动器和扫描驱动器供电的电源; 以及电压电平控制器,其基于与视频数据对应的图像电平来控制电子发射装置的阴极电极和栅电极之间的电压差。 利用这种配置,在低图像级别的情况下,图像的对比度高,并且在高图像水平的情况下功率消耗受到限制,并且防止电子发射装置劣化。
