Abstract
A storage device allocates a thermal region tag (TRT) to a meta block based on a programming temperature and other conditions that may affect an optimal TRT parameter. A controller in the storage device programs a meta block and obtains a current temperature, a first TRT associated with the current temperature, and a parameter associated with the first TRT when closing the meta block. The controller determines that the first TRT has been active for more than a predefined active period, a temperature fluctuation across a predefined number of thermal regions occurred during previous meta blocks programming, and/or a number of meta blocks assigned to the first TRT is greater than a TRT compaction threshold. The controller deactivates the first TRT, allocates a second TRT to a thermal region including the current temperature, and assigns the second TRT to the meta block.
