Abstract
A controller-bridge architecture in which a bridge device coupled with the non-volatile memory (NVM) handles inline read-modify-write function under instructions from a controller device is disclosed. In some embodiments, instead of transferring an entire range of data (e.g., a whole NVM page) across a bus between the bridge and the controller twice (once before and once after modification), only the modification data is sent by the controller to the bridge across the bus. The bridge in some embodiments also handles error correction and/or RAID parity striping in the read-modify-write process.
