  • ELECTRONIC DEVICE USING EXTERNAL MEMORY DEVICE TO STORE HARDWARE SETTING OF SEMICONDUCTOR CHIP FOR FAST BOOT AND POWER SAVING OF SEMICONDUCTOR CHIP
    Publication number: 20230280913
    Abstract: An electronic device includes a semiconductor chip and a first memory device. The semiconductor chip includes an input/output (I/O) interface circuit. The first memory device is external to the semiconductor chip. The semiconductor chip communicates with the first memory device via the I/O interface circuit. The semiconductor chip stores at least one hardware setting of the semiconductor chip into the first memory device before a power-off event of the semiconductor chip.

  • Bucket-based wear leveling method and apparatus
    Patent number: 9251056
    Abstract: A method for memory management is provided for a memory including a plurality of pages. The method comprises assigning in-use pages to in-use buckets according to use counts. The in-use buckets include a low in-use bucket for a lowest range of use counts, and a high in-use bucket for a highest range of use counts. The method comprises assigning free pages to free buckets according to use counts. The free buckets include a low free bucket for a lowest range of use counts, and a high free bucket for a highest range of use counts. The method maintains use counts for in-use pages. On a triggering event for a current in-use page, the method determines whether the use count of the current in-use page exceeds a hot swap threshold, and if so moves data in the current in-use page to a lead page in the low free bucket.
