WebbThree major points arise from the simulations concerning the sharp changes in the behavior of the selected variables at the beginning and following the end of the retention policy: (1) it is important to recognize the existence, origin, and shape of patterns of variable behavior; (2) retention effects lingered long after the policy ended--the …
Webb2.3 Variable Retention Time DRAMs have always exhibited variable retention time (VRT) phenomena. Currently, there are no efficient ways of fundamentally pre-screening VRT bits during produc-tion testing. So far, most manufacturers have been able to manage it by increasing average retention time and by enforcing larger test screen margin.
