Phison Low-Level Format Tool v3.9.0.0 is designed for PS2251 series controller chips, supporting PS2251-01, PS2251-02, PS2251-07, and other main controllers.

: The chip relies on embedded MaskROM and a dedicated chunk of internal RAM. Crucially, the controller has no internal flash memory for its own code. Instead, upon power delivery, the MaskROM bootloader scans the attached external NAND flash memory chips for a valid firmware header, copies that firmware into the internal RAM, and executes it. Instead, upon power delivery, the MaskROM bootloader scans

serve as vital repositories for these rare firmware binaries, helping users extend the life of their hardware.

The controller complies with USB 3.0 specifications, supporting theoretical data transfer speeds up to 5 Gbit/s (625 MB/s), although actual performance is limited by the NAND flash speed. 2. Versatile NAND Support (MLC/TLC) upon power delivery
