Device operations

Read ONFI signature
To recognize NAND flash devices that are compatible with the ONFI 1.0 command set, the
Read Electronic Signature can be issued, followed by an address of 20h. The next four
bytes output is the ONFI signature, which is the ASCII encoding of the ‘ONFI’ word. Reading
beyond four bytes produces indeterminate values. The device remains in this state until a
new command is issued.
provides the definition of the output bytes.

Read parameter page
The Read Parameter Page command retrieves the data structure that describes the NAND
flash organization, features, timings and other behavioral parameters. This data structure
enables the host processor to automatically recognize the NAND flash configuration of a
device. The whole data structure is repeated at least five times.
See Figure 40 for a description of the read parameter page waveform.
The Random Data Read command can be issued during execution of the read parameter
page to read specific portions of the parameter page.
The Read Status command may be used to check the status of read parameter page during
execution. After completion of the Read Status command, 00h is issued by the host on the
command line to continue with the data output flow for the Read Parameter Page command.
Read status enhanced is not be used during execution of the Read Parameter Page
command.
Table 21 defines the parameter page data structure; for parameters that span multiple bytes,
the least significant byte of the parameter corresponds to the first byte.
Values are reported in the parameter page in bytes when referring to items related to the
size of data access (as in an x8 data access device). For example, the chip returns how
many data bytes are in a page. For a device that supports x16 data access, the host is
required to convert byte values to word values for its use. Unused fields are set to 0h.
For more detailed information about parameter page data bits, refer to ONFI
specification 1.0, section 5.4.1.
