An external connection terminal connector as a separate part that mounts the igniter is abolished, and the external connection terminal is integrated with the igniter itself. Such a system and method is implemented in software operating such that control of the real memory usage in the computer system is transparent to the operating system. The method may be employed for forming within magnetoresistive sensor elements magnetoresistive layers with enhanced dimensional uniformity, and in particular enhanced overlay dimensional uniformity. The control channel field, C, bits include one flag bit and two data bits.
