摘要： A dual resistance heater for a phase change material region is formed by depositing a resistive material. The heater material is then exposed to an implantation or plasma which increases the resistance of the surface of the heater material relative to the remainder of the heater material. As a result, the portion of the heater material approximate to the phase change material region is a highly effective heater because of its high resistance, but the bulk of the heater material is not as resistive and, thus, does not increase the voltage drop and the current usage of the device.

摘要： A chalcogenide material and chalcogenide memory device having less stringent requirements for formation, improved thermal stability and/or faster operation. The chalcogenide materials include materials comprising Ge, Sb and Te in which the Ge and/or Te content is lean relative to the commonly used Ge2Sb2Te5 chalcogenide composition. Electrical devices containing the instant chalcogenide materials show a rapid convergence of the set resistance during cycles of setting and resetting the device from its as-fabricated state, thus leading to a reduced or eliminated need to subject the device to post-fabrication electrical formation prior to end-use operation. Improved thermal stability is manifested in terms of prolonged stability of the resistance of the device at elevated temperatures, which leads to an inhibition of thermally induced setting of the reset state in the device. Significant improvements in the 10 year data retention temperature are demonstrated. Faster device operation is achieved through an increased speed of crystallization, which acts to shorten the time required to transform the chalcogenide material from its reset state to its set state in an electrical memory device.
摘要翻译：一种硫族化物材料和硫族化物记忆装置，其对形成，改进的热稳定性和/或更快的操作要求不太严格。硫属化物材料包括Ge，Sb和Te的材料，其中Ge和/或Te含量相对于通常使用的Ge 2 Sb 2 Te 5硫族化物组合物是稀的。包含瞬时硫族化物材料的电气装置显示设定循环期间的设定电阻的快速收敛以及将器件从其制造状态复位，从而导致减少或消除了将器件置于后制造电形成之前最终使用操作。改进的热稳定性表现在器件在升高的温度下的电阻的延长的稳定性，这导致抑制器件中复位状态的热诱导设置。展示了10年数据保存温度的显着改进。通过提高结晶速度实现更快的器件操作，其用于缩短将硫族化物材料从其复位状态转换到其在电存储器件中的设定状态所需的时间。

摘要： A memory employs a low-level current source to access a phase change memory cell. The current source charges an access capacitor in order to store sufficient charge for an ensuing access. When a memory cell is accessed, charge stored on the capacitor is discharged through the phase change memory, supplying a current to the phase change memory cell that is sufficient for the intended access operation and greater than that provided directly by the current source.
