Abstract: Several systems and methods of chip select are described. In one such method, a device maintains two identifiers, (ID_a and ID_m). When the device receives a command, it examines the values of ID_a and ID_m relative to a third reference identifier (ID_s). If either ID_a or ID_m is equivalent to ID_s, the device executes the command, otherwise, the device ignores the command. By using two different identification methods, a system has options in choosing to activate devices, being able to selectively switch between selecting multiple devices and single devices in a quick manner. In another such method, a device may have a persistent area that stores identification information such as an ID_a. Thus, system functionality may remain independent from any defect/marginality associated with the physical or logical components required for initial ID_a assignment of all devices in the system.

Abstract: Some embodiments include a memory device and a method of programming memory cells of the memory device. One such method includes applying voltages to data lines associated with different groups of memory cells during a programming operation. Such a method applies the voltages to the data lines associated with a last group of memory cells being programmed in a different fashion from the other groups of memory cells after the other groups of memory cells have been programmed. Other embodiments including additional memory devices and methods are described.

Abstract translation: 描述了芯片选择的几种系统和方法。 在一种这样的方法中，设备维护两个标识符（ID_a和ID_m）。 当设备接收到命令时，它检查ID_a和ID_m相对于第三参考标识符（ID_s）的值。 如果ID_a或ID_m等于ID_s，则设备执行该命令，否则设备将忽略该命令。 通过使用两种不同的识别方法，系统具有选择激活设备的选项，能够以快速方式选择多个设备和单个设备之间进行选择性切换。 在另一种这样的方法中，设备可以具有存储诸如ID_a的标识信息的持久区域。 因此，系统功能可以独立于与系统中所有设备的初始ID_a分配所需的物理或逻辑组件相关联的任何缺陷/边际。

Abstract: Apparatus, methods, and systems are disclosed, including those to improve program voltage distribution width using automatic selective slow program convergence (ASSPC). One such method may include determining whether a threshold voltage (Vt) associated with a memory cell has reached a particular pre-program verify voltage. In response to the determination, a voltage applied to a bit-line coupled to the memory cell may be automatically incremented at least twice as the program voltage is increased, until the cell is properly programmed. Additional embodiments are also described.
