Abstract
An apparatus comprising a memory and a controller. The memory may be configured to process a plurality of read/write operations. The memory comprises a plurality of memory modules each having a size less than a total size of the memory. The controller is configured to provide a first redundancy scheme when user data occupies less than a preconfigured limit and a second redundancy scheme that protects less than all of the user data when the user data occupies greater than the preconfigured limit.
Claims12
An apparatus comprising:
- a memory configured to process a plurality of read/write operations, said memory comprising a plurality of memory modules each having a size less than a total size of said memory;
- and
- a controller configured to provide (a) a first redundancy scheme when user data occupies less than a preconfigured limit and (b) a second redundancy scheme that protects less than all of the user data when the user data occupies greater than the preconfigured limit.
An apparatus comprising:
- an interface configured to connect to a memory configured to process a plurality of read/write operations, said memory comprising a plurality of memory modules each having a size less than a total size of said memory;
- and
- a processor configured to provide (a) a first redundancy scheme when user data is a first type and (b) a second redundancy scheme that protects less than all of the user data when the user data is a second type.
