开放式NAND闪存接口工作组（Open NAND Flash Interface Working Group）今天宣布了他们的ONFI 1.0 NAND闪存规范，旨在从硬件层次上为NAND闪存的设计制造建立一个统一的标准。

ONFI规范规定了闪存芯片的指令，寄存器，针脚，电气性能以及封装等各种参数。还规定闪存可以通过一种标准化的协议和控制器进行通讯自报家门，让控制器可以自动设定时序等参数。

ONFI还宣布，将会在今年6月发布ONFI第二版规范，提高传输速度，增加“块提取功能”简化控制器设计，集成纠错码，为存储器和I/O模块单独供电减少干扰等。

ONFI工作组最早由Intel在去年春季IDF上宣布成立，现有37家成员，包括海力士，美光，Phison，索尼，ATI，Cypress，Genesys，富士康，Marvell，Seagate，Sigmatel，WinBond等。
