We still use wear levelling and product lifetime tests, where samples are tested to destruction by reading and writing continually. During test, we look at latency, and success of operation. That reminds me to check the results for the most recent second source eMMC we brought into the BOM. ;-) I think John's comment about the industry rate of change still apply. Devices are going end-of-life quicker than before. --=20 James Cameron http://quozl.linux.org.au/ --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
