One embodiment of the face seal described herein includes a seal seat and a seal element carried by a seal housing. If the memory controller receives a data transfer request related to a read or write burst which will stay within a page of memory, the first input command decoder circuit generates a first input command which is then passed, in sequence, by the first and second multiplexers. In the process according to the present invention, the deactivation of catalyst due to dissolution of silicon in the catalyst can be reduced, thus lifetime of the catalyst extended and the stable operation time elongated. According to this method, VDIFF is increased by an increment less than a transistor threshold voltage.
