Read ID2
The device contains an alternate identification mode, initiated by writing 30h-65h-00h to the command
register, followed by address inputs, followed by command 30h. The address for S34ML01G1 will be
00h-02h-02h-00h. The address for S34ML02G1 and S34ML04G1 will be 00h-02h-02h-00h-00h. The ID2 data
can then be read from the device by pulsing RE#. The command register remains in Read ID2 mode until
further commands are issued to it.
shows the Read ID2 command sequence.
3.18
Read ONFI Signature
To retrieve the ONFI signature, the command 90h together with an address of 20h shall be entered (i.e. it is
not valid to enter an address of 00h and read 36 bytes to get the ONFI signature). The ONFI signature is the
ASCII encoding of 'ONFI' where 'O' = 4Fh, 'N' = 4Eh, 'F' = 46h, and 'I' = 49h. Reading beyond four bytes yields
indeterminate values.
