Micron Technology had two patents in mobile during Q4 2023. Micron Technology Inc filed a patent for utilizing non-traditional refresh schemes in non-volatile memory, based on statistical data for decay of capacitance within memory cells. Error-tolerant applications benefit from enhanced memory bandwidth with reduced or eliminated refresh operations, while error-intolerant applications actively refresh cells or regions not adequately refreshed over time.

Application: Methods and apparatus for probabilistic refresh in volatile memory devices (Patent ID: US20230410873A1)
The patent filed by Micron Technology Inc. focuses on methods and apparatus for implementing non-traditional refresh schemes in non-volatile memory. The approach involves characterizing memory performance based on statistical data for decay of capacitance within memory cells over time, allowing for error-tolerant applications to operate with reduced or eliminated refresh operations, thereby enhancing memory bandwidth. Error-intolerant applications, on the other hand, actively refresh cells or regions of memory not adequately refreshed by presumed random read/write operations. The patent also describes a computing device with multiple memory devices of varying performance levels, where an application can access a lower-performance memory device for a period of time before replacing its contents with a higher-performance memory device.
The claims in the patent detail the configuration of the computing device and the non-transitory computer-readable apparatus to execute applications with error tolerance, operate memory devices without refresh logic, or at a reduced rate of refresh based on specified performance levels. The apparatus is designed to select refresh rates based on probabilistic characterizations of the memory device and adjust refresh rates based on parameters associated with the memory device. Overall, the patent introduces innovative techniques for optimizing memory performance in various applications by utilizing non-traditional refresh schemes tailored to specific performance requirements and characteristics of the memory devices.
