AI Technical Summary
Existing storage devices in critical systems like autonomous vehicles face a fatal issue when they reach a maximum bad block state, necessitating a read-only mode that halts data updates, which is undesirable due to the essential need for data updates in such systems.
A storage device with a storage controller that manages bad blocks by maintaining the over-provisioning area capacity and adjusting the user area capacity based on the number and ratio of bad blocks, postponing the transition to a read-only mode and sending replacement notifications.
This approach prevents immediate transition to read-only mode, maintaining system functionality and performance by allowing controlled capacity adjustments and timely replacement notifications, thus avoiding operational disruptions.
