Provided is a method of assembly for a noise suppressor using specific welding and assembly procedures. In the multi-port memory device having a data transmissionreception block which exchanges data with the global data bus in a current sensing type data transmissionreception structure, an initialization switch is used to discharge each global data bus line and an initialization signal generator controls the initialization switch. Processing pipelines are used to demodulate, transcode and index the content transmissions to produce content data that are streamed to users.
