pm1735 is equipped with Samsung tlcv-nand particles.

"Memory particles" is a name for memory chips in Hong Kong and Taiwan (only for memory), and other chips are called "chips".

After the chip is packaged, it becomes a flash memory particle.

The difference between original chips and white chips

Memory chips are divided into original (major brand or simply major, the original trademark of the printed chip)/white chips/defective (downgraded) .

"White films" can be subdivided into ett, utt and other worse grades. Those traded in the formal market are generally major, ett, and utt.

UTT's name is untested, which means it has not been tested, but in fact the most basic physical tests are still done, while ET's name is effectively tested, which means particles that have passed the effectiveness test. The testing process is much more than that of UTT. Less, but the quality is much better. But none of them have gone through the same rigorous testing as the original major particles.

Original particles are generally tested through physical conditions to simulate the aging of the particles after working for a long time in a harsh environment for several years (but the particles will not really age). Can they pass this test? The particles can certainly ensure the stability of long-term use. Only such particles are eligible to be marked with the original manufacturer's mark.
