Abstract: Apparatus, systems, and methods may operate to receive an external erase command at a control circuit coupled to an erasable memory array located on a substrate. A global select gate voltage may thereafter be enabled for application to wordline transistors coupled to the erasable memory array after a voltage applied to the substrate has reached a preselected initiation voltage level between about zero volts and an ultimate erase voltage.
Abstract translation: 装置，系统和方法可以操作以在耦合到位于基板上的可擦除存储器阵列的控制电路处接收外部擦除命令。 之后可以使全局选择栅极电压施加到耦合到可擦除存储器阵列的字线晶体管，在施加到衬底的电压已经达到约零伏特和最终擦除电压之间的预先选择的初始电压电平之后。

Abstract: The apparatus and systems described herein may comprise a plurality of memory cells coupled to a local wordline, and a wordline drive circuit that includes a regulator coupled to a plurality of pass transistors and a string driver. The regulator may comprise a regulator transistor having a threshold voltage that is substantially the same as the threshold voltage of the string driver during memory cell program operations. In some embodiments, the regulator may comprise a cascode-connected pair of transistors. Methods of manufacturing and operating the apparatus and systems are also described.
