Abstract
The present disclosure generally relates to methods of operating storage devices. The storage device comprises a controller comprising first random access memory (RAM), second random access memory (RAM), and a storage unit divided into a plurality of zones. By restricting the host to have a minimum write size, the data transfer speed to RAM, RAM, and the storage unit can be optimized. A temporary buffer is utilized within the RAMto update parity data for the corresponding commands. The parity data is updated in the RAMand written to the RAMin the corresponding zone. The parity data may be copied from the RAMto the RAMto update the parity data in the temporary buffer when commands are received to write data to corresponding zones. As the parity data is updated, the corresponding command is simultaneously written to the corresponding zone.
