VARIABLE REDUNDANCY IN A SOLID STATE DRIVE

摘要

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.
