A method begins by a processing module generating an integrity check value for each encoded data slice of a set of encoded data slices to produce a set of integrity check values. 01 to 5% by weight copolymer of acrylic acid and methacrylic acid, and balance water, wherein the copolymer of acrylic acid and methacrylic acid has a monomer ratio in the range of 1:30 to 30:1 and the copolymer has a molecular weight in the range of 1K to 1000K. An insulating film is formed on the main surface of the semiconductor chip so as to expose at least one of the plurality of electrodes. The read assist circuit may be configured to improve read reliability by partially discharging the at least one bit line from an already precharged voltage level to a lower third voltage level in preparation to read data from the memory cell. The control device includes a microprocessor and a control input device used for receiving an input setting value.
