US Patent 7903463 Increased NAND flash memory read throughput

A method of reading sequential pages of flash memory from alternating memory blocks comprises loading data from a first page into a first primary data cache and a second page into a second primary data cache simultaneously, the first and second pages loaded from different blocks of flash memory. Data from the first primary data cache is stored in a first secondary data cache, and data from the second primary data cache is stored in a second secondary data cache. Data is sequentially provided from the first and second secondary data caches by a multiplexer coupled to the first and second data caches.
