  • Publication number: 20200304155
    Abstract: Provided herein is an error correction decoder and a memory system having the same. The error correction decoder includes a memory configured to store a hard decision value of a variable node. The decoder further includes a flipping function value generator configured to generate, in an i-th iteration, a first value based on a number of unsatisfied check nodes (UCNs) corresponding to the variable node, and to generate a flipping function value as (i) a difference between the first value and an offset value or (ii) a set value, wherein i is a non-negative integer. The decoder also includes a comparator configured to output, in the i-th iteration, a first signal indicating whether to flip or not flip the hard decision value of the variable node in the memory based on comparing the flipping function value to a flipping threshold value.

  • Publication number: 20200280075
    Abstract: Provided are stainless steel for a separator of a polymer electrolyte membrane fuel cell, which exhibits enhanced hydrophilicity and enhanced corrosion resistance, and a method of manufacturing the same. In the stainless steel for a separator of a polymer electrolyte membrane fuel cell, which exhibits enhanced hydrophilicity and enhanced corrosion resistance, according to an embodiment of the present invention, a ratio of Cr hydroxide/Cr oxide included in a passivation film of the stainless steel ranges from 0.5 to 1.7, and the passivation film has a contact angle (?) of 70° or less. Thus, not only corrosion resistance may be enhanced by removing a non-conductive film formed on a surface of the stainless steel and forming a new conductive film thereon, but hydrophilicity may also be secured without additional surface treatment such as a separate coating or the like, and thus manufacturing costs may be reduced and productivity may be increased.
