HP Reports Memory Resistor Breakthrough

andy1307 writes "Hewlett-Packard scientists on Thursday will report advances demonstrating significant progress in the design of memristors, or memory resistors. The researchers previously reported in The Proceedings of the National Academy of Sciences that they had devised a new method for storing and retrieving information from a vast three-dimensional array of memristors. The scheme could potentially free designers to stack thousands of switches on top of one another in a high-rise fashion, permitting a new class of ultra-dense computing devices even after two-dimensional scaling reaches fundamental limits."

Re:Heat?

[HiThere]

Yes. Memristors don't require that power be applied in order to retain memory state. Heat might limit write and retrieval rate, but it wouldn't limit the number of layers. I suspect that it might make heat pipes built into the memory boards to be a highly desirable option, but that would be to enable faster access, not to allow a greater number of layers.
