摘要: NOR型FLASH存储器因其能够长久地保持数据的非易失性(Non-Volatile)特点,被广泛用作各类便携型数字设备的存储介质,但由于此类器件的编程及擦写均需写入特定指令,以启动内置编程/擦除算法,从而使得采用自动测试系统对其进行测试也具有较高难度。因此,研究NOR型FLASH存储器的测试技术,并开发此类器件的测试平台具有十分重要的意义。首先以AMD公司的AM29LV160DT为例,介绍了NOR型FLASH存储器的基本工作原理,接着详细阐述了一种采用J750EX系统的DSIO模块动态生成测试矢量的方法,从而能够更为简便、高效地对NOR型FLASH存储器的功能进行评价。

Abstract: Flash memory of NOR type because of the characteristics which can keep data for a long time(non-volatile), is widely used as storage medium for all kinds of portable digital equipment, but because this type of device programming and erasing are required to write specific instructions, to start the built-in program/Erase algorithm, which makes the automatic test system test it very difficultly, therefore, research to testing technology for Flash memory of NOR type, and the developing test platform of such devices,are both very important. In the paper, taking AM29LV160DT(AMD, Inc.)as an example,we first introduce its basic working principle, and then expatiate detailedly on the method of generating test vector dynamically used by the DSIO module of J750EX system.Thus we can evaluate the function of Flash memory of NOR type more conveniently and efficiently.

Key words: NOR type FLASH, DSIO
