WebbSo essentially, this is a measure of how good you are at retaining your existing customers #4 - Customer Retention Cost (CRC) This is a measure of your costs associated with retaining customers ... 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 ...

Did you know?
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 … 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 ...
