On June 4, 1968, the DRAM patent filed by IBM’s Robert H. Dennard was granted. To commemorate this anniversary and highlight the evolution of the technology, we have asked some of the manufacturers in our portfolio about their track record in DRAM and how they view the future of the technology. One of them is Winbond, one of the top 5 memory suppliers globally thanks to its expert capabilities of product design, R&D and manufacturing of customer-driven products. When did you enter DRAM? Winbond was established in 1987 and successfully developed the first 64K SRAM in 1991. In 1995, we started to develop the manufacturing process with partners and started our first own 8-inch fab in 1997. In 2000 we joined the Fujitsu-Toshiba DRAM development program with 0.13um trench DRAM technology and opened our first 12-inch Taiwan fab in 2004. Winbond’s first mass- produced and self-developed 46nm process technology started from 2011 onwards after we secured a DRAM technology transfer from ..
