Methods of and apparatuses for matching the signal delay, clock timing, frequency response, gain, offset, andor transfer function of signal pathways in electrical circuits such as, for example, time-interleaved and pipelined circuits using analog-valued floating-gate MOSFETs are disclosed. For each file or directory whose parent directory resides on a remote server, the server owning the file or directory produces a shadow directory structure. The code may be provided to the client as part of a content response. The placement region sizes are based on estimates of the needed buffers. Di is set to Diddi, where dd0d1. A schedule merging device is further provided to merge the plurality of schedule scripts into a merged schedule.
