Abstract: A method and apparatus is provided for individually checking, sanitizing and/or otherwise altering data bits of a plurality of memory chips via one or more processes where the memory chips being processed at any given time may be of different unformatted memory capacities, may be of different memory types, and may have the process started at different times. The method utilizes a computer based program capable of multithreaded operation whereby a new procedure thread is initiated upon a determination by the main program that a given reader port is in recent initial communication with a memory chip.
