Over the past 12 years, Winbond has devoted itself to the flash memory market, increasing its product competitiveness and improving market share. In 1995, Winbond manufactured its first 5V flash memory in a 6-inch fab. In 2003, using its 0.18 μm WinStack process technology in an 8-inch fab, Winbond manufactured 4 Mb, 8 Mb FWH and LPC low-density flash memories, achieving a market share of over 50% in motherboard products. In 2007, Winbond launched the W19B family of 16 Mb, 32 Mb and 64 Mb parallel flash memories, manufactured using WinStack technology. With this expanded product range, Winbond was able to extend flash memory applications beyond PC-related fields to the areas of consumer electronics and networking.
The W19B160B and W19B320B are 16 Mb and 32 Mb devices, respectively, supporting x8/x16 data widths. Random access speed can reach 70 ns at operating voltages of 2.7V-3.6V. Major features include erase Suspend/Erase resume, Top or Bottom Boot Block, Write-Protection and Hardware Reset. They are ideal for DVD players and recorders, MP3 players, printers, networking, set-top boxes, projectors, automotive applications, consumer electronics, gaming devices and mobile devices. In addition, the 32 Mb W19B320B offers a security sector to protect critical code for customers.
The 64 Mb W19B640C supports all W19B320B features and also includes 20 ns page mode access speed and Flexible Bank architecture, for simultaneous read/write operation. It is ideal for consumer applications such as DSC, DVD recorder, STB(DVB-C), high-end networking applications and low-price handsets. All W19B family package/pinouts and command sets are JEDEC standard compatible.
In 2008, to maintain its competitive edge, Winbond plans to manufacture 16 Mb, 32 Mb, 64 Mb and 128 Mb parallel flash memories, using Winbond's leading 0.09 μm WinStack process technology.
