1. A method, comprising:
determining a correlation between optimal reference voltage offsets and a signal counts metric associated with a solid-state storage device;
in response to a decoding failure of a codeword read from a first memory of the solid-state storage device, obtaining at least three read values of the codeword;
calculating a signal counts metric value from the at least three reads;
computing an optimal reference voltage offset from the signal counts metric and the correlation;
determining a new center read reference voltage based on a current center reference voltage and the optimal reference voltage offset; and
performing at least one subsequent read of the codeword following the decoding failure utilizing the new center read reference voltage.
