Winbond Product Highlight - QspiNAND Flash


Winbond, a renowned provider of memory solutions, has unveiled a range of QspiNAND Flash products with a standard SPI interface and a bus width of x1/x2/x4. These products, which are available in densities of 512Mb, 1Gb, 2Gb, and 4Gb, operate at a nominal voltage of either 1.8V or 3.3V.



In an effort to simplify the process of storing code on NOR Flash systems with densities above 512Mb, Winbond is also offering QspiNAND products with the same SPI interface in 1Gb and 2Gb densities. While NOR Flash may be more cost-effective at lower densities, NAND Flash becomes a more cost-effective option at densities of 512Mb and above.


In addition to their cost-effectiveness, QspiNAND products from Winbond also offer the benefit of a smaller package size, which can lead to cost savings in manufacturing processes such as PCB cost and others. For those looking for a reliable and cost-effective memory solution, Winbond's QspiNAND products are an excellent choice.


Code Shadowing

Code stored in Flash memory is often transferred to DRAM for faster execution by the processor, a process known as code shadowing. To facilitate this process, system designers seek out products that can quickly and efficiently transfer code from Flash to DRAM.


Winbond offers a solution with their "Continuous Read" & “Sequential Read” functionalities, which enables the rapid transfer of the contents of NAND to DRAM. This feature is particularly useful for those looking to optimize the performance of their systems and ensure smooth and efficient code execution.


By choosing a memory solution with this functionality, system designers can be confident that they are selecting a product that can keep up with the demands of their applications. If you need a high-performing memory solution that can quickly transfer code from Flash to DRAM, consider Winbond's NAND products with Continuous Read functionality.
