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. The controller restricts the host to a maximum number of zones that can be in the open and active state at a time. Open zones can be switched to the closed state, and vice versa, upon a predetermined amount of time expiring. The maximum number of open zones is based on one or more amounts of time to: generate parity data, copy the parity data from the RAM2 to the RAM1, update the parity data, switch a zone from the open and active state to the closed state, and the amount of space in a temporary RAM1 buffer.
