Abstract
A system and method for storing compressed data in a memory system includes identifying user data to be compressed and compressing pages of user data to form data extents that are less than or equal to the uncompressed data. A plurality of compressed pages are combined to a least fill a page of the memory. The data may be stored as sectors of a page, where each sector includes a CRC or error correcting code for the compressed data of that sector. The stored data may also include error correcting code data for the uncompressed page and error correcting code for the compressed page. When data is read in response to a user request, the sector data is validated using the CRC prior to selecting the data from the read sectors for decompression, and the error correcting code for the uncompressed page may be used to validate the decompressed data.
