    • A bitline selection network is composed of a plurality of bitlines and a plurality of global bitlines. The bitlines are grouped into bytes with eight bitlines per byte. The bitlines provide access to memory cells for read and write operations. A bitline is connected to a global bitline through a bitline select transistor. Each of the bitline select transistors is activated one at a time by a bitline select controller. Activation of each bitline select transistor provides a connection to a source line, which in turn connects to a sense amplifier and a write data loading logic block. The sense amplifier and the write data loading logic block are used in read and write operations respectively.
    • 位线选择网络由多个位线和多个全局位线组成。 每个字节将位线分成8个位线的字节。 位线提供对存储器单元的访问以进行读取和写入操作。 位线通过位线选择晶体管连接到全局位线。 每个位线选择晶体管由位线选择控制器一次激活。 每个位线选择晶体管的激活提供与源极线的连接,源极线又连接到读出放大器和写入数据加载逻辑块。 读写放大器和写数据加载逻辑块分别用于读写操作。

    • A high-voltage charge pump circuit includes a charge pump circuit. A first high-voltage output circuit is configured to set an output voltage of the charge pump at a first voltage level selected for regular programming and erasing memory cells. A second high-voltage output circuit is configured to set the output voltage of the charge pump at a second voltage level selected for walkout of device junctions, the second voltage level being higher than the first voltage level. A third high-voltage output circuit is configured to set the output voltage of the charge pump at a third voltage level selected for guardband programming and erasing, the third voltage level being lower than the second voltage level and higher than the first voltage level. Selection circuitry selectively couples one of the first, second, and third high-voltage output circuits to the output of the high-voltage charge pump circuit.
    • 高压电荷泵电路包括电荷泵电路。 第一高压输出电路被配置为将电荷泵的输出电压设置为为常规编程而选择的第一电压电平并擦除存储器单元。 第二高电压输出电路被配置为将电荷泵的输出电压设置为选择用于器件结的迂回的第二电压电平,第二电压电平高于第一电压电平。 第三高压输出电路被配置为将电荷泵的输出电压设置为选择用于保护带编程和擦除的第三电压电平,第三电压电平低于第二电压电平并高于第一电压电平。 选择电路将第一,第二和第三高压输出电路中的一个选择性地耦合到高压电荷泵电路的输出。
