基于FPGA的NAND FLASH控制器

主要介绍现场可编程阵列FPGA在NAND FLASH芯片测试仪系统中的应用,由于芯片本身内部结构非常复杂,还可以允许坏块的存在,而且坏块的数目在使用过程中还可以增加,这使得对芯片进行操作变得非常难,而利用FPGA对NAND FLASH进行控制,可以非常方便地对他进行读写、擦除以及坏块判断等几种重要的操作,从而能快捷、准确、稳定地测试出芯片的好坏,为NAND FLASH厂商和用户提供更为准确的判断依据。

NAND FLASH Controller Based on FPGA

The paper mainly introduces FPGA in the chip tester system application.As the chip itself is very complicated structure,it allows the existence of bad blocks,the number of bad blocks in the use of the process can still increase,it operats the chip has become very difficult.And the use of NAND FLASH FPGA control,it is very convenient for reading,writing,erasing and bad block judgment of several pieces of important operational.So it can quickly and accurately test the stability of the chip is good or bad for NAND FLASH manufacturers and users with a more accurate basis for the judgment.
