== Notes ==
*All offsets on the index page are absolute. Offsets on subpages are relative within each section (unless otherwise mentioned)
*eMMC is mapped in the same way as NAND. It uses 256Mb, the GameOS deviceID is identical & all the NAND offsets from the table above can be safely used. 
*NOR and NAND are [http://en.wikipedia.org/wiki/Block_%28data_storage%29 blockdevices] and thus:
**The minimal chunk of data that can be read/written is a block (with flashdevices also named page). A block that has never been written (only erased/formatted) is filled with 0xFF's. When bytes are written to a block, the entire block must be written. The write process fills the nonused bytes (slack space) at the remainder of the block with 0x00's
**1 block = 512 bytes (0x200) which conveniently correlates to the standard [http://en.wikipedia.org/wiki/Disk_sector sectorsize] used on magneto/optical drives

== Common Flash Interface (CFI) ==

An access to the common flash interface can be enabled by writing to the physical address space of flash memory device, for example, you can use ps3sbmmio driver on Linux.

Enter CFI
{{Keyboard|content=<syntaxhighlight lang="bash">
printf '\x98\x98' | dd of=/dev/ps3sbmmio bs=1 count=2 seek=$((0x1f0000aa))
</syntaxhighlight>}}

Dump CFI tables
{{Keyboard|content=<syntaxhighlight lang="bash">
for i in {0..127}; do dd if=/dev/ps3sbmmio bs=1 count=1 skip=$((0x1f000001+$i*2)) >> cfi_tables.bin 2>/dev/null; done;
xxd cfi_tables.bin
</syntaxhighlight>}}

Exit from CFI
{{Keyboard|content=<syntaxhighlight lang="bash">
printf '\xf0\xf0' | dd of=/dev/ps3sbmmio bs=1 count=2 seek=$((0x1f000000))
</syntaxhighlight>}}

Here is an output from Slim console (JTP-001):
