Abstract

A memory device with an age-detect-and-correct (ADAC) circuit that detects skew caused by bias temperature instability fatigue (that is, bias temperature instability stress accumulated over time), and counters skew by selectively adjusting the proportion (measured temporally) of active state operation to idle state operation. Also, a memory burn-in device using a similar ADAC circuit.
