    摘要: A first conductive electrode material is formed on a substrate. Chalcogenide comprising material is formed thereover. The chalcogenide material comprises AxSey. A silver comprising layer is formed over the chalcogenide material. The silver is irradiated effective to break a chalcogenide bond of the chalcogenide material at an interface of the silver comprising layer and chalcogenide material and diffuse at least some of the silver into the chalcogenide material. After the irradiating, the chalcogenide material outer surface is exposed to an iodine comprising fluid effective to reduce roughness of the chalcogenide material outer surface from what it was prior to the exposing. After the exposing,. a second conductive electrode material is deposited over the chalcogenide material, and which is continuous and completely covering at least over the chalcogenide material, and the second conductive electrode material is formed into an electrode of the device.

    摘要: A method for refreshing PCRAM cells programmed to a low resistance state and entire arrays of PCRAM cells uses a simple refresh scheme which does not require separate control and application of discrete refresh voltages to the PCRAM cells in an array. Specifically, the array structure of a PCRAM device is constructed to allow leakage current to flow through each programmed cell in the array to refresh the programmed state. In one embodiment, the leakage current flows across the access device between the anode of the memory element and the bit line to which the cell is connected, for each memory cell in the array which has been programmed to the low resistance state. In another embodiment, the leakage current flows to the programmed cells through a doped substrate or doped regions of a substrate on which each cell is formed. An entire array is refreshed simultaneously by forming each memory element in the array to have one common anode formed as a single cell plate for the array. Only PCRAM cells in the array written to the low resistance state are refreshed by the controlled leakage current, whereas cells in the high resistance state are not affected by the refresh operation.
