Abstract
A memory system or flash card may include an algorithm or process for managing the handling of large tables in memory. A delta may be used for each table to accumulate updates. There may be a plurality of deltas for a multi-level delta structure. In one example, the first level delta is stored in random access memory (RAM), while the other level deltas are stored in the flash memory. Multiple-level deltas may improve the number of flash writes and reduce the number and amount of each flush to the actual table in flash. The use of multi-level deltas may improve performance by more efficiently writing to the table in flash.
