NAND Error Rate<br />
� Bit Error Rate<br />
– Fail<strong>in</strong>g bits corrected with appropriate levels of ECC<br />
– Correctable bit errors do not result <strong>in</strong> data loss<br />
� Raw Bit Error Rate (RBER): Bit error rate<br />
prior to ECC<br />
� Uncorrectable Bit Error Rate (UBER): Bit<br />
error rate after ECC<br />
� UBER is projected us<strong>in</strong>g the measured RBER<br />
and specific level of ECC<br />
