Abstract:
A data storage apparatus includes a nonvolatile memory device and a controller configured to decode on normal read data read from a target memory cell, calculate a standard deviation of history read voltages for a target memory block including the target memory cell when the decoding of the normal read data fails, compare the calculated standard deviation with a preset first threshold value and a preset second threshold value, and determine a decoding type and a decoding order for the target memory cell based on a comparison result.

Claim (Index 6):
The data storage apparatus of  claim 2 , wherein the processor controls the ECC unit to sequentially perform the first soft-decision decoding, the second hard-decision decoding, and the second soft-decision decoding on the target memory cell when the standard deviation is equal to or larger than the second threshold value.
