Definition and Terminology of Industrial SSD Temperature - Part I

When the temperature rises, both physical and chemical processes are accelerated. This is particularly true regarding damage to NAND flash memory cells. In other words, using NAND flash at high temperatures can significantly reduce its durability. Due to its sensitivity to changes in the characteristics of the insulating layer, this effect is more pronounced in high-density flash that stores multiple threshold levels.
To maximize the lifespan of NAND flash, the flash memory controller needs to monitor and adapt to these changes. Both variations in ambient temperature and temperature cycles caused by powering the device on and off exert physical stress on the components, as different materials expand and contract at different rates. This can ultimately lead to the failure of electrical connections.
