Abstract
A method for detecting storing states of a solid state storage device is provided, including steps of: applying sensing voltages to memory units; comparing threshold voltages of the memory units with the sensing voltages and accordingly to define the storing states including a strong correct region, a weak correct region, a strong error region and a weak error region, in which the memory units are classified; calculating the number of the memory units in the storing states; calculating a strong correct ratio of the number of the memory units in the strong correct region to the number of the memory units in the strong and weak correct regions; calculating a strong error ratio of the number of the memory units in the strong error region to the number of the memory units in the strong and weak error regions; and generating a log-likelihood ratio based on said ratios.
