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. With ...

WebbVariable Retention Time (VRT). VRT refers to the tendency of some DRAM cells to shift between a low (leaky) and a high (less leaky) retention state, which is shown to be ubiquitous in modern DRAMs [29]. Since the retention time of a DRAM cell may change due to VRT, DRAM cells may have long retention times during testing but shift to short ...
