Abstract
Systems and methods for storing data in a multi-level cell (MLC) flash memory are disclosed. One such data storage system has a data path with cascaded data access performance, including multiple storage portions having different data access speeds. A cascaded data path enables flash memory data access that has a more graceful degradation instead of an abrupt decrease in performance during operation.
