Wear-Level<strong>in</strong>g Example<br />
� MLC devices can typically support 10,000 cycles per<br />
block<br />
� If you erased and reprogrammed one block every<br />
second, you would exceed the 10,000 cycl<strong>in</strong>g limit <strong>in</strong><br />
just 3 hours!<br />
60 x 60 x 3 = 10,080<br />
� Rather than cycl<strong>in</strong>g the same block, wear-level<strong>in</strong>g<br />
<strong>in</strong>volves distribut<strong>in</strong>g the number of blocks that are<br />
cycled<br />
