Emulated EEE Memory Partitioning for Endurance

The patent divides the non-volatile memory into multiple partitions (first NVM partition, second NVM partition, etc.) and divides the volatile memory into corresponding portions. Each partition stores data for specific volatile memory portions, allowing selective wear distribution across partitions. This segmentation enables the system to achieve improved endurance for frequently updated data without requiring a proportional increase in total non-volatile memory capacity, thereby controlling costs while maintaining reliability.

The patent implements dynamic wear leveling through a wear indicator mechanism that tracks the number of erase cycles for each NVM partition. The system dynamically redirects future erase operations from worn partitions to less-worn partitions based on these indicators. This dynamic adaptation allows the same physical memory size to provide extended endurance by evenly distributing wear across all partitions over time, preventing any single partition from reaching its endurance limit first.
