Winbond Serial NAND Flash for code storage nand flash semiconductor

Winbond provides a series of Serial NAND products compatible with SPI NOR interface, so that users do not need to continue to rack their brains over the selection of large-capacity memory. In the past, NOR Flash has a relatively good cost advantage in low-volume products, but NAND Flash is a more cost-competitive product in large-volume products.

Advantages of Winbond Serial NAND:

Built ECC

Traditional NAND requires additional controller to manage, detect and correct some problems that NAND may encounter during operation, such as bad block management, ECC correction, etc. But winbond Serial NAND products built-in ECC (Error Correcting Code Error correction Code) function, but also provides a continuous good "block" (block) Serial NAND, these can let the user does not need additional controller, can easily enjoy the function brings the convenience and practicality.


Continuous Read

In a typical system startup, the code is stored in flash memory and then read out at startup so that the CPU can run faster in DRAM. This process is known as code mapping. One of the goals of system designers is to be able to read code from flash memory into DRAM more quickly. The unique "Continuous Read" function of huabang is one of the functions specially designed to make the code in NAND Read out in a faster way.
