1. A method, executed by one or more processors, for sorting flash memories, the method comprising:
testing, via the one or more processors, a failure metric for each of a plurality of flash memories over a plurality of testing sessions to capture failure metric data that corresponds to the plurality of flash memories; weighting, via the one or more processors, the failure metric data according to the testing session; determining, via the one or more processors, a trend in the failure metric as a function of testing cycles for each of the plurality of flash memories from the failure metric data; repetitively conducting testing sessions, via the one or more processors, until a selected confidence level is attained for the trend in the failure metric as a function of testing cycles; clustering, via the one or more processors, the trends in the failure metric as a function of testing cycles to provide a plurality of clustered groups for the failure metric data; physically separating the plurality of flash memories into routing groups and routing the routing groups via equipment controlled by the one or more processors, according to the plurality of clustered groups; wherein the failure metric comprises grown bad blocks; and wherein the plurality of clustered groups comprise a scrap or rework group, an acceptable quality group, and an exceptional quality group and routing the routing groups comprises routing the scrap or rework group to scrapping or reworking stations within a manufacturing environment. |
