Allocating thermal region tags in a storage device

A method for allocating a thermal region tag (TRT) to a meta block in a storage device based on a programming temperature and other conditions that may affect an optimal TRT parameter, the storage device includes a controller to execute the method comprising:

• programming a first meta block;
• obtaining a current temperature, a first TRT associated with the current temperature, and a parameter associated with the first TRT when closing the meta block;
• determining if a condition exists to affect the optimal TRT parameter;
• and
• if the condition exists, deactivating the first TRT, allocating a second TRT to a thermal region including the current temperature, and assigning the second TRT to the first meta block.

A storage device to allocate a thermal region tag (TRT) to a meta block based on a programming temperature and other conditions that may affect an optimal TRT parameter, the storage device comprises:

• a memory device including meta blocks to store host and control data;
• a controller to:
• program the meta block,
• obtain a current temperature, a first TRT associated with the current temperature, and a parameter associated with the first TRT when closing the meta block,
• determine that at least one of 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 a number of meta blocks assigned to the first TRT is greater than a TRT compaction threshold, and
• deactivate the first TRT, allocate a second TRT to a thermal region including the current temperature, and assign the second TRT to the meta block.
