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 7):
The data storage apparatus of  claim 6 , wherein the processor determines whether or not the first soft-decision decoding is successful and controls the ECC unit to perform the second hard-decision decoding when the first soft-decision decoding fails, and\n the processor determines whether or not the second hard-decision decoding is successful and controls the ECC unit to perform the second soft-decision decoding when the second hard-decision decoding fails.
