    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.

    摘要: A memory element, a threshold switching element, or the series combination of a memory element and a threshold switching element may be used for coupling conductive lines in an electrically programmable matrix array. Leakage may be reduced by optionally placing a breakdown layer in series with the phase-change material and/or threshold switching material between the conductive lines. The matrix array may be used in a programmable logic device.

    摘要: A phase-change material is proposed for coupling interconnect lines an electrically programmable matrix array. Leakage may be reduced by optionally placing a thin insulating breakdown layer between the phase change material and at least one of the lines. The matrix array may be used in a programmable logic device. The logic portions of the programmable logic device may be tri-stated.

    摘要: A thin-film memory may include a thin-film transistor-free address decoder in conjunction with thin-film memory elements to yield an all-thin-film memory. Such a thin-film memory excludes all single-crystal electronic devices and may be formed, for example, on a low-cost substrate, such as fiberglass, glass or ceramic. The memory may be configured for operation with an external memory controller.

    摘要: A phase change memory cells including a memory element or a threshold device is read using a read current which does not threshold either the memory element or the threshold device in the case of both a set and a reset memory element. As a result, higher currents may be avoided, increasing read endurance. A sensing circuit includes a charging rate detector coupled to a selected address line and sensing a rate of change of a voltage on the selected address line.

    摘要: A phase change memory may be utilized in place of a dynamic random access memory in a processor-based system. The memory may keep track of the number of read or write cycles so that it may determine when a refresh cycle will occur. During the refresh cycle, the phase change memory may implement other tasks not related to a refresh because the phase change memory does not need to be refreshed. Typical of such tasks may be determining whether any bits are weakly programmed or improperly programmed and taking corrective action with respect to those bits.
