Methods for dynamically programming and dynamically reading one or more resistive change elements within a resistive change element array are disclosed. These methods include first pre-charging all of the array lines within a resistive change element array simultaneously and then grounding certain array lines while allowing other array lines to float in order to direct discharge currents through only selected cells. In this way, resistive change elements within resistive change element arrays made up of 1-R cells,that is, cells without in situ selection circuitry,can be reliably and rapidly accessed and programed. 公开了用于对电阻变化元件阵列内的个或多个电阻变化元件进行动态编程和动态读取的方法。这些方法包括：首先同时对电阻变化元件阵列内的所有阵列线进行预先充电，并且然后将某些阵列线接地，同时允许其他阵列线浮动从而引导放电电流仅通过所选单元。以这种方式，可以对由1-R单元--即不具有原位选择电路的单元--组成的电阻变化元件阵列内的电阻变化元件进行可靠且快速的访问和编程。
