    摘要: A phase change memory may be read so as to reduce the likelihood of a read disturb. A read disturb may occur, for example, when a reset device is raised to a voltage, which causes its threshold device to trigger. The triggering of the threshold device produces a displacement current which may convert a reset device to a set device. By ensuring that the reset cell never reaches a voltage that would result in triggering of the threshold device, read disturbs may be reduced.
