Unique ID，可以理解为独一无二的ID，读取命令为：EDh（command）+00h（address）

脚本如下：

将脚本保存为“EDh00h.ssl”载入NFA100软件中，得到结果如下：

NFA100 Ver2.0 Beta6.5
Script Execution Result

 B2 A1 E6 54 D0 48 00 A0 FF 00 FF 00 FF 00 FF 00

那么，如何知道Nand Flash是否支持UID的功能呢？在厂商提供的规格书中，ONFI Parameter Page data structure表格中描述如下:

第8个Byte的第5个bit 如果是“1”，则支持Read UID功能。

运行脚本：

'Command(0 Address, 0 Data)
CMND00 0 EC 0 0
'Send Address(1 Address)
SNDAD1 0 00 0
'Receive data and save to the result file
GETDAT 0 00FF 0 1    //获取255个Bytes的结果

得到如下结果：

4F 4E 46 49 FE 03 F8 DD FF 3F 0F 00 03 00 3D 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 4D 49 43 52 4F 4E 20 20 20 20 20 20 4D 54 32 39 46 32 35 36 47 30 38 43 42 43 42 42 4A 34 20 20 2C 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 40 00 00 A0 08 00 00 00 00 00 00 00 04 00 00 90 08 00 00 01 23 02 94 00 03 03 01 00 00 01 00 FF 02 1E 00 00 00 00 00 00 00 00 00 00 00 00 00 02 3F 00 00 00 C4 09 30 75 64 00 90 01 3F FF 02 23 00 10 00 23 00 05 03 67 00 96 00 00 00 1B 44 00 00 01 00 02 00 01 00 00 00 03 10 01 81 04 02 04 01 1C 90 10 FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 09 BA

其中Byte 8-9为FFh，3Fh，说明此Nand Flash支持Read Unique ID
