The PS4 Non Volatile Storage (NVS) is, like in PS3 and PS Vita, a storage that has two properties: it remains accessible after electricity shortage (unlike RAM) and it is non-removeable (unlike HDD). NVS is mostly used for storing tokens and flags.
Same as PS3's NVS, used for storing tokens and flags. You can access it by using the function icc_nvs_read (or by ftp'ing the respective regions with root flags server).<br>
Seems that a total of 7 regions(blocks) exist in 2 banks, main bank and backup bank <br>
The kernel accesses only the 5th and the 2nd region, however it's possible to read the other 5 (also the entirety of it by reading /dev/sflash0s0x34 with BUF_SIZE 0x200 from ftp ).<br>
Most, if not all, of the NVS regions can be accessed also in sflash, starting with offset 0x1C4000.


On PS4, there are 2 Non Volatile Storages, one in the [[Serial Flash]] and one in the [[Syscon]] EEPROM. On PS3, NVS is stored in Serial Flash (NAND or NOR) whilst on PS Vita, NVS is part of Syscon EEPROM. There is also the Secure NVS (SNVS), which is a secure area of the Syscon NVS. SNVS is encrypted with some SAMU keys and can be accessed only after doing a handshake.

Syscon NVS is accessible from EMC but only after doing the handshake to unlock EMC functionalities.
 
= Serial Flash NVS =
 
PS4 [[Serial Flash]] NVS is usually stored at offset 0x1C4000 (it depends on the Serial Flash MBR). The size of the whole Serial Flash NVS is 0xC000 bytes.
 
Serial Flash NVS can be accessed from Kernel by calling the function icc_nvs_read. It can also be read by calling IO functions, with System privileges, to open <code>/dev/sflash0s0x34</code>.
 
== Serial Flash NVS Banks ==
 
A total of 7 blocks exist in 2 banks: main bank and backup bank. The kernel makes use only of the bank 0 block 4 and the bank 1 block 1, even though it is possible to read/write the other 5 banks. Indeed, <code>/dev/sflash0s0x34</code> access is provided to System applications and to Kernel.
