Abstract
An adaptive data-retention-voltage regulating system for static random-access memory (SRAMs) is revealed. The system includes a power supply unit, a data-retention-voltage (DRV) monitor cell for monitoring static noise margin (SNM) of SRAM, a data loss detector for generating a data loss signal, and a dynamic regulating controller that receives the data loss signal for generating a refresh signal and a switch signal.
