Read Identification (RDID)

The READ ID command is used to read the 2 bytes of identifier code programmed into the NAND

Flash device. The READ ID command reads a 2-byte table (see below) that includes the

Manufacturer ID and the device configuration.



Manufacturer identification (one byte)



Device identification (one byte)

Any Read Identification (RDID) instruction while an Erase or Program cycle is in progress is not

decoded, and has no effect on the cycle that is in progress.

The instruction sequence is shown in Figure 10

The Read Identification (RDID) instruction is terminated by driving Chip Select (CS#) High at

any time during data output.

When Chip Select (CS#) is driven High, the device is put in the Standby Power mode. Once in

the Standby Power mode, the device waits to be selected, so that it can receive, decode and

execute instructions.
