Patent ID: 8850104

Claim:
A data storage method, comprising: in a set of data items associated with respective logical addresses for storage in a memory, identifying a first subset of the logical addresses associated with the data items containing application data, and a second subset of the logical addresses associated with the data items containing parity information that has been calculated over the application data; storing the data items associated with the first identified subset in one or more first physical memory areas of the memory, and storing the data items associated with the second identified subset in one or more second physical memory areas of the memory, different from the first physical memory areas; performing a memory management task independently in the first physical memory areas and in the second physical memory areas; and accepting the set of the data items and the respective logical addresses from a host; wherein identifying the first and second subsets comprises identifying one or more parameters of a redundant storage scheme used by the host to produce the data items containing the parity information, and identifying the first and second subsets based on the parameters.
