摘要:
A memory array (140) includes first and second sets of conductors (142), (144) and a plurality of memory-diodes (130), each connecting in a forward direction a conductor (BL) of the first set (142) with a conductor (WL) of the second set (144). An electrical potential is applied across a selected memory-diode (130), from higher to lower potential in the forward direction, intended to program the selected memory-diode (130). During this intended programming, each other memory-diode (130) in the array (140) has provided thereacross in the forward direction thereof an electrical potential lower than its threshold voltage. The threshold voltage of each memory-diode (130) can be established by applying an electrical potential across that memory-diode (130) from higher to lower potential in the reverse direction. By so establishing a sufficient threshold voltage, and by selecting appropriate electrical potentials applied to conductors of the array (140), problems related to current leakage and disturb are avoided.
摘要(中):
存储器阵列(140)包括第一和第二组导体(142),(144)和多个存储器二极管(130),每个存储器二极管(130)在前向方向上与第一组(142)的导体(BL) 第二组(144)的导体(WL)。 在所选择的存储器二极管(130)上施加电势,从正向上的较高电位到较低的电位,用于对所选择的存储器二极管(130)进行编程。 在该期望的编程期间,阵列(140)中的每个其它存储器二极管(130)在其正向方向上提供了低于其阈值电压的电位。 每个存储二极管(130)的阈值电压可以通过在该存储二极管(130)上施加从相反方向的较高电位到较低电位的电位来建立。 通过这样建立足够的阈值电压,并且通过选择施加到阵列(140)的导体的适当电势,避免了与电流泄漏和干扰有关的问题。
