    摘要: A voltage memory switch may be formed of an amorphous semiconductor threshold switch and a select device. The amorphous threshold switch may be latched into one of two different current conducting levels. Then, in some embodiments, a relatively dense memory array can be achieved by maintaining an appropriate bias on the cell to prevent it from losing the programmed state.

    摘要: A phase change memory including a threshold device, such as an ovonic threshold switch, and a storage device may be read. Reading the cell may involve applying a first voltage to a selected cell and then a second voltage, lower than the first voltage. The first voltage may be sufficient to threshold the ovonic threshold switch if the storage device is in the set state.
