System and method for dynamic adjustment of SSD critical temperature threshold based on memory size
A system and method for dynamically adjusting a critical temperature threshold of non-volatile memory to ensure full capture of information to non-volatile memory before the information handling system hibernates. If the operating temperature of the non-volatile memory reaches a critical temperature threshold, a controller determines the memory size of information in volatile memory. If there is a maximum memory size, the controller uses the default critical temperature threshold as the critical temperature threshold and initiates a process to write information to the non-volatile memory and hibernates the system. If there is less than the maximum memory size, the controller may dynamically increase the critical temperature threshold based on the memory size such that the information in volatile memory can be written to the non-volatile memory before the information handling system hibernates.
