StrataFlash，它是一款由英特尔公司制作的存放每个细胞2或3比特而不是一个多重细胞(MLC)的闪存技术。横跨各细胞的电压被划分成四个等级， 使能其中任意一个2比特的可能组合为： 00, 01, 10或11。StrataFlash技术在英特尔的ETOX闪存产品的基础上进行了发展。 每个细胞3比特的技术，达到了电压的八个等级。

StrataFlash是NOR型（或非）闪存，通过多值逻辑在1个存储单元存储2bit信息。

StrataFlash:

A multilevel cell (MLC) flash memory technology from Intel that stores two or three bits per cell rather than one. The voltage across each cell is divided into four levels, enabling any of the possible combinations of two bits: 00, 01, 10 or 11. The StrataFlash technology evolved out of Intel's ETOX flash memory products. Three bits per cell are achieved with eight levels of voltage.
