A PC card and a method of controlling the PC card is provided which can be used to add multiple capabilities to an information processing apparatus in cooperation with a conventional card only by the use of a single card slot. The field transistor includes a gate conductive layer pattern formed on a field oxide layer. The present invention also provides a method of manufacturing a single crystal using the fixing method. Furthermore, the systems and methods include overlaying the first plot with the second plot based at least in part on the first feature of interest and the corresponding second feature of interest. The method identifies whether the value of unused bits of the or each target operand affects the value of the target operation and whether the target operand or any of the target operands is capable of having one or more unused bits of inappropriate value.
