The invention is the use and application of a system having a non-toxic and biodegradable surfactant, which is not ethoxylated and is built up from alkyl polyglycoside derivatives, for use in the oilfield industry to mitigate the release of toxic chemicals into the environment. The write-protection control circuit may store start and end block addresses of an unlock region of the non-volatile memory array, and selectively activate a write enable signal according to the relationship between a write address and the start and end block addresses. The processing device is adjusted to the web material used by way of the read in property data.
