K9K1G08R0B SAMSUNG [Samsung semiconductor], K9K1G08R0B Datasheet - Page 37

• Manufacturer Part Number: K9K1G08R0B
• Description: 128M x 8 Bit NAND Flash Memory
• Manufacturer: SAMSUNG [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 but must be don’t-cared for
1.8V device. The command register remains in Read ID mode until further commands are issued to it. Figure 20 shows the operation
sequence.
