Abstract
A memory system or flash card may include a controller that indexes a global address table (GAT) with a single data structure that addresses both large and small chunks of data. The GAT may include both large logical groups and smaller logical groups for optimizing write amplification. The addressing space may be organized with a large logical group size for sequential data. For fragmented data, the GAT may reference an additional GAT page or additional GAT chunk that has a smaller logical group size.
