Abstract:
1. A system including non-Flash re-writeable non-volatile memory, comprising: a semiconductor substrate including circuitry fabricated on the semiconductor substrate, the circuitry including a processor and a memory controller in electrical communication with each other; a memory plane in direct contact with and fabricated directly above the semiconductor substrate; at least one re-writeable two-terminal non-volatile cross-point memory array embedded in the memory plane and including a plurality of first conductive array lines orthogonally oriented to a plurality of second conductive array lines to form a plurality of cross-points, the plurality of first and second conductive array lines are in electrical communication with the memory controller; and a plurality of re-writeable non-volatile two-terminal memory elements, each memory element is positioned between one of the cross-points and has a first terminal directly electrically coupled with the first conductive array line at its respective cross-point and a second terminal directly electrically coupled with the second conductive array line at its respective cross-point, wherein the memory controller is specifically configured to perform data operations on the at least one re-writeable two-terminal non-volatile cross-point memory array without having to perform an erase operation prior to a write operation and to perform random access data operations on the at least one re-writeable two-terminal non-volatile cross-point memory array at a data granularity ranging from a single bit of data in a single memory element to at least one block of data in a subset of the plurality of re-writeable non-volatile two-terminal memory elements, and wherein the memory controller is configured to perform at least some data operations on the at least one re-writeable two-terminal non-volatile cross-point memory array using a file structure including a header section, a data section, and a footer section.
