AFTER BECOME 3D FLASH COMPANY HAVE A BIG BENEFIT
FOR EXAMPLE
FOR 32GB USB3 .SILICON POWER MARVEL M50
IN 2013 =SM3267 +ORGINAL INTEL L74 (4CE)
IN 2014=SM3267 +SANDISK TLC (2CE )
IN 2020 ALSO LOW COST CONTROLLER +DOWNGRADED NAND 32GB (ONLY 1CE )
OK 1CE TLC ?? MAXIMUM WRITE SPEED IS 10MB (SOME SAY OH NOT 8T23. I WORK 2 YEARS 8T23
IN 3D FLASH JUST INTEL MICRON MLC L06 IS VERY GOOD EACH 1 CE (MLC 16K 3D CAN WRITE SPEED 30MB
HOW EVER

after extract nand i read it (8t22 98 3c 98 b3)
install on big controller 2251-09
8t22 can work vccq =3.3 volt
but do remember
intel n18 l06 and b16 b17 vccq must 1.8 volt
if you put 3.3 on im flash may be nand is destroyed
in smi r44 for 3d (1.8)volt
but i just install nand and work normal and
it is very easy
and copy all important file
WE NEED 2251-09-26 DATA (HAVE IMPORTANT FAMILY WEDDING MOVIE
I HAVE ANOTHER 2251-09 BUT THIS MODEL HAVE LM3020 IC TO 1.8 VOLT VCCQ
SO FIRST EXTRACT NAND FROM 2251-09-26
AND INSTALL ON OTHER PCB
