SCALING LARGE DRIVES USING ENHANCED DRAM ECC

The present disclosure generally relates to solid state storage device and techniques for conserving storage capacity associated therewith. Several embodiments are presented, including a data storage device, data storage controller, and methods for using the same are provided in the subject disclosure. A data storage device includes: a plurality of memory devices, a controller coupled to the plurality of memory devices and configured to program data to and read data from the plurality of memory devices, a memory including a logical-to-physical address translation map configured to enable the controller to determine a physical location of stored data in the plurality of memory devices, where the logical-to-physical address translation map contains at least one entry that merges at least two addresses that map, respectively, to at least two physical locations in the plurality of memory devices, where the controller is configured to encode each merged entry with an error-correcting code.
