The Code Storage Flash Memory family consists of NOR, NAND and TrustME® Secure Flash Memories. Winbond is the #1 supplier of Serial Flash products in the industry and is the largest unit supplier of NOR flash memories. In this SpiFlash® family, products range in densities from 512Kb through 1Gb mostly in small 8-pin packages, in addition to 16-pin SOIC and 24-ball BGA packages at 3V and 1.8V with speeds up to 133MHz.
The SLC NAND flash memories are offered in densities from 1Gb through 4Gb in JEDEC standard packages and are compliant to the ONFi standard. As an extension to the SpiNOR family, Winbond offers QspiNAND flash products in 1Gb and 2Gb densities with special features like continuous read which facilitates fast data transfer between flash and DRAM on system designs. The QspiNAND products have built-in ECC and bad block management which simplifies the management of NAND. All of these flash products are available as KGD (Known Good Die) as well. A family of Multi Chip Package (MCP) NAND + DRAM products are also offered ranging from 1Gb through 4Gb densities at 1.8V primarily used in mobile and other applications.
With AEC-Q100, TS16949, ISO9001/14001, OHSAS18001 qualifications, flash memory products are available in Industrial grade and several of these products are qualified for Automotive grade. These products in the flash memory family are used in computer, communication, consumer, mobile, automotive and industrial applications.
