According to foreign media reports, Samsung’s new semiconductor factory in Pyeongtaek, Gyeonggi-do, South Korea will start operations in July. It is understood that this is the largest chip factory in the world with an area of ​​2.89 million square meters. It will begin construction in 2015 and will cost 15.6 trillion won, or approximately RMB 94 billion. The factory will be mainly used to mass produce Samsung's fourth-generation 3D NAND flash memory chips, vertical stacking up to 64 layers, monthly production capacity will reach 450,000 wafers, 3D flash memory accounts for more than half. However, it takes a few years for the plant to fully operate and reach its maximum capacity, so there will be no apparent mitigation of the current high prices of flash and SSDs. The Ethernet switch is a switch based on Ethernet to transmit data, and the Ethernet uses a local area network that shares a bus-type transmission medium. The structure of the Ethernet switch is that each port is directly connected to the host, and generally works in full-duplex mode. The switch can connect to many pairs of ports at the same time, so that each pair of hosts that communicate with each other can transmit data without conflict as if it were an exclusive communication medium.
