    • A memory arrangement and method of operating a memory arrangement is disclosed. In one embodiment of the memory arrangement according to the invention, rewritable memory cells are arranged at crossovers between word lines and bit lines, said memory cells being configured in such a manner that the information stored in them is essentially read out in a nondestructive manner. According to the invention, the memory arrangement has a flag cell either for each word line or for each bit line, said flag cell being able to store an item of information that indicates whether at least one of the memory cells either along the respective word line or along the respective bit line has been subjected to a reading operation since a basic state occurred.
    • 公开了一种操作存储装置的存储装置和方法。 在根据本发明的存储器装置的一个实施例中,可重写存储器单元被布置在字线和位线之间的交叉处,所述存储器单元被配置为使得存储在其中的信息基本上以非破坏性方式读出。 根据本发明,存储器装置对于每个字线或对于每个位线具有标志单元,所述标志单元能够存储指示存储器单元中的至少一个沿着相应字线的信息项 或者沿着相应的位线已经进行了基本状态的读取操作。

    • A memory element comprises a resistance element having a first resistance value in a first state and a second resistance value in a second state, it being possible to convert the resistance element from the first state into the second state and from the second state into the first state and the first resistance value and the second resistance value being different, a current generating device, coupled to a first terminal of the resistance element, the current generating device being designed to generate a current with a first amplitude through the resistance element when a predetermined potential is present at a second terminal of the resistance element, in order to convert the resistance element into the first state for setting the first resistance value, or to generate a current with a second amplitude through the resistance element when the predetermined potential is present at the second terminal of the resistance element, in order to convert the resistance element into the second state for setting the second resistance value, the first resistance value representing a first memory state and the second resistance value representing a second memory state.
    • 存储元件包括具有第一状态的第一电阻值和第二状态的第二电阻值的电阻元件,可以将电阻元件从第一状态转换为第二状态并从第二状态转换为第一状态 状态,并且所述第一电阻值和所述第二电阻值不同;电流产生装置,耦合到所述电阻元件的第一端子,所述电流产生装置被设计成当预定的电流值产生具有第一振幅的电流时, 电位存在于电阻元件的第二端子处,以便将电阻元件转换成用于设定第一电阻值的第一状态,或者当预定电位存在于电阻元件时通过电阻元件产生具有第二幅度的电流 电阻元件的第二端子,以便将电阻元件转换成第二端子 状态,用于设定第二电阻值,第一电阻值表示第一存储状态,第二电阻值表示第二存储状态。
