Abstract
The present disclosure generally relates to methods of operating storage devices. The storage device comprises a controller comprising first random access memory (RAM1), second random access memory (RAM2), and a storage unit divided into a plurality of zones. A first command to write data to a first zone is received, first parity data for the first command is generated in the RAM1, and the data of the first command is written to the first zone. When a second command to write data to a second zone is received, the generated first parity data is copied from the RAM1 to a parking section in the storage unit, and second parity data associated with the second zone is copied from the parking section to the RAM1. The second parity data is then updated in the RAM1 with the data of the second command and copied to the parking section.
