Ming Huang - Oak Park CA, US

International Classification:

G06F 12/00

US Classification:

711103, 711E12001

Abstract:

The present invention provides a non-volatile flash memory management system and method that provides the ability to efficiently manage a large array of flash devices and allocate flash memory use in a way that improves reliability and longevity, while maintaining excellent performance. The invention mainly comprises of a processor, an array of flash memories that are modularly organized, an array of module flash controllers and DRAM caching. The processor manages the above mention large array of flash devices with caching memory through mainly two tables: Virtual Zone Table and Physical Zone Table, a number of queues: Cache Line Queue, Evict Queue, Erase Queue, Free Block Queue, and a number of lists: Spare Block List and Bad Block List.

Abstract:

The present invention provides a novel flash memory connection method between a flash controller and flash devices such that the controller can manage two or more flash devices concurrently. It provides the ability to efficiently manage a large array of non-volatile flash devices in a solid state drive (SSD) and allocate flash memory usage in such a way that at least doubles the SSD bandwidth and the total storage capacity.
