Abstract
A system and method for reducing write amplification while maintaining a desired level of sequential read and write performance is disclosed. A controller in a multi-bank flash storage device may receive host data for writing to the plurality of flash memory banks. The controller may organize the received data in multi-page logical groups greater than a physical page and less than a physical block and interleave writes of the host data to the memory banks with that striping factor. A buffer RAM is associated with each bank of the multi-bank memory where the buffer RAM is sized as equal to or greater than the size of the multi-page logical group.
