ONFI READ ID Operation
90h
The ONFI READ ID function identifies that the device supports the ONFI specification. If
the device supports the ONFI specification, then the ONFI signature will be returned.
The ONFI signature is the ASCII encoding of ONFI:
• O = 4Fh
• N = 4Eh
• F = 46h
• I = 49h.
Reading beyond these four values yields indeterminate data. Figure 16 defines the ONFI
READ ID behavior and timings.
Issuing a 90h command to the command register and a 20h command to the address
register puts the device into ONFI read ID mode. The device will remain in this mode
until another valid command and address are issued. If a 90h command is issued with-
out an address, the device will remain in the ONFI read ID mode.
