    摘要: A partition may be made up of two planes of memory cells in a phase change memory. These planes may be configured so that they are not adjacent to one another. In some embodiments, this may mean that the adjacent planes may share sensing circuits, reducing the overall size of the memory array. In addition, by using non-adjacent planes to make up a partition, the planes may be spaced in a way which reduces resistance of power conveying lines. This may mean that smaller sized lines may be used, further reducing the size of the overall array.

    摘要: A phase-change memory device includes a plurality of data PCM cells for storing data bits; data decoding circuits for selectively addressing sets of data PCM cells; and data read/program circuits for reading and programming the selected data PCM cells. The device further includes a plurality of parity PCM cells for storing parity bits associated with data bits stored in the data PCM cells; parity decoding circuits for selectively addressing sets of parity PCM cells; and parity read/program circuits for reading and programming the selected parity PCM cells.

    摘要: A phase change memory may be organized with a global word line coupled to a plurality of blocks, each with a plurality of phase change memory cells arranged in rows and columns. Thus, one global word line may be common to a plurality of blocks. The global word line may be coupled to a word line decoder that is responsible for pulling the word line to ground. Each of the blocks, on the other hand, is coupled to a bitline selector through a bitline. Each block may have its own local word line coupled to the global word line. In some cases, this architecture reduces the minimum capacity of the memory.
