20140281162 | ADAPTIVE REFERENCE TUNING FOR ENDURANCE ENHANCEMENT OF NON-VOLATILE MEMORIES - A wear leveling technique is employed in a memory device so that the cycling history of a memory block is represented by the cycling history of a representative memory cell or a small number of representative memory cells. A control logic block tracks the cycling history of the one or more representative memory cells. A table tabulating the predicted shift in an optimal value for a reference variable for a sensing circuit as a function of cycling history is provided within the memory device. Prior to sensing a memory cell, the control logic block checks the total number of cycling in the one or more representative memory cells and adjusts the value for the reference variable in the sensing circuit, thereby providing an optimal value for the reference variable in the sensing circuit for each sensing cycle of the memory device. | 09-18-2014 |

20150032979 | SELF-ADJUSTING PHASE CHANGE MEMORY STORAGE MODULE - A dynamic self-adjusting memory storage device and method of operating. The device includes a plurality of adjustable-size phase change memory (PCM) storage sub-modules connected to and communicating over a bus with a control device. One of the plurality of adjustable-size memory storage sub-modules is in a stand-by mode of operation. The control device implements steps to: determine, based on a switching criteria, when the memory storage device needs to be switched to a different operation mode; select one or more adjustable-sized memory storage sub-modules for switching to said different operation mode; copy stored data from a selected actively operating adjustable-size memory storage sub-module to said adjustable-size memory storage sub-module in said stand-by mode; and change the capacity of the selected actively operating adjustable-size memory storage sub-module after the copying. The dynamic self-adjusting memory capacity method is performed without powering down the memory storage device or paying any timing penalty. | 01-29-2015 |
