VOLTAGE ADJUSTMENT BASED ON MEMORY DEVICE TEMPERATURE PROFILING
Abstract
This patent describes a data storage system designed to enhance memory device reliability and performance. It achieves this by intelligently adjusting internal operating voltages – such as pass-through, bit line bias, or source line voltages – based on a determined "cross-temperature condition." This condition is established through real-time temperature profiling, specifically by measuring both the program (write) and read temperatures associated with virtual memory blocks. This dynamic voltage adaptation optimizes memory operation and mitigates temperature-related operational challenges, thereby improving data integrity and device longevity.
