Architecture to allow efficient storage of data on NAND flash memory

摘要

Systems, methods, apparatus, and techniques are provided for writing data to a storage medium. A stripe of the storage medium is interfaced via one or more data transfer channels, where the stripe comprises a plurality of pages of the storage medium. A data stream is received and the data stream is portioned into a plurality of allocation units (AUs), where each AU in the plurality of AUs has a pre-determined byte length. A first portion of a selected AU from the plurality of AUs is written to a first page of the plurality of pages and a second portion of the selected AU is written to a second page of the plurality of pages by consecutively writing bytes of the selected AU from a starting byte on the first page to an ending byte on the second page.

主权项

1. A system for writing data to a storage medium, the system comprising:
interface circuitry configured to interface with a stripe of the storage medium via one or more data transfer channels, the stripe comprising a plurality of pages of the storage medium; partition circuitry configured to receive a data stream and partition the data stream into a plurality of allocation units (AUs), each AU in the plurality of AUs having a same pre-determined byte length; and write circuitry configured to write a first portion of a selected AU from the plurality of AUs to a first page of the plurality of pages and a second portion of the selected AU to a second page of the plurality of pages by consecutively writing bytes of the selected AU from a starting byte on the first page to an ending byte on the second page.
