A method for analyzing an unverified executable file within an antivirus engine in order to identify the executable file as being obfuscated by an unknown obfuscator program is described. Each bank includes at least two memory planes having corresponding page buffers, where any number and combination of the memory planes are selectively accessed at the same time in response to configuration data and address data. The measured potential-derivative is compared with a preferred anode potential-derivative of an anode charge curve or an anode discharge curve, and with a preferred cathode potential-derivative of a cathode charge curve or a cathode discharge charge curve. This laser can be used wherever a TEA CO2 laser with conventional gas mixture containing helium is used.
