4 Gbit (512M x 8 bit) NAND Flash
3.19 Read ID.
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an
address input of 00h.
The 5-byte Read ID configuration are supported: The device operating mode (5-byte) is selected through cam setting.
3.19.1 Legacy Read ID
Five read cycles sequentially output the manufacturer code (20h), and the device code and 3rd, 4th, and 5th cycle ID,
respectively. The command register remains in Read ID mode until further commands are issued to it. Figure 27 shows
the operation sequence, while Table 14 to Table 18 explain the byte meaning. Complete read id code table is as
follows.
