K9K1G08U0A Samsung semiconductor, K9K1G08U0A Datasheet - Page 40

• Manufacturer Part Number: K9K1G08U0A
• Description: 128M x 8 Bit / 64M x 16 Bit NAND Flash Memory
• Manufacturer: Samsung semiconductor

Read ID
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of
00h. Four read cycles sequentially output the manufacture code(ECh), and the device code*, Reserved(A5h), Multi plane operation
code(C0h) respectively. A5h must be don’ t-cared. C0h means that device supports Multi Plane operation. The command register
remains in Read ID mode until further commands are issued to it. Figure 23 shows the operation sequence.
