What Are the Original and White Chips of Flash Memory?

In fact, white film is just a popular folk saying. For manufacturers, there are only good die and inked die, which are good product particles and bad particles. Good die encapsulated by flash memory manufacturers is the original film, and good die encapsulated by third-party manufacturers is what we call white film.

So it sounds like there's no difference between the original film and the white film? After all, white chips are just a popular name without a clear definition. Flash memory on SSD that does not use original packaging is basically called that. In fact, most white chips are actually good dies packaged by third parties. The source of these good dies is mainly to buy wafers from wafer manufacturers, cut and package them themselves, or buy cut dies for packaging, Theoretically, the product quality is the same as that of the original flash memory, but it depends on the quality control of each factory.

Larger storage manufacturers such as Kingston and Weigang have their own packaging plants, so their SSDs basically have their own logos, while smaller manufacturers basically do not have their own factories. They will buy finished products directly from the OEM, such as qunlian. It is the master manufacturer, but they also sell complete solutions, including flash memory, There are quite a lot of Toshiba flash memory packaged by qunlian in the market. In fact, Toshiba is the major shareholder of qunlian, and the Toshiba flash memory packaged by qunlian is quite reliable.

Of course, the main reason why consumers pursue the original film is that most people can't distinguish the quality of white film, because in terms of quality control, various manufacturers have their own standards, and the quality of good die is uneven. However, manufacturers generally don't indiscriminately use flash memory with poor quality, otherwise they will be dragged down by after-sales repair at any time. However, the market determines everything, Some of them are classified by the original manufacturer as flash memory that can not reach the quality of good die but can not reach the quality of inked die, or some inked die that can be used again after being monitored by the packaging factory will become degraded chips. However, after these degraded chips are packaged, it is difficult to distinguish them from the third-party sealed good die. They are all divided into the field of white chips.

Since everyone can't tell the good from the bad, it's good to directly choose the SSD of the original flash memory. However, there are quite few manufacturers using the original SSD, except those who produce their own flash memory. Maybe some manufacturers will use the original for some high-end products, and quite few manufacturers use the original for all, Because most of the original films are sold to servers and enterprise applications, they can make higher profits in these fields, and the rest are digested by their own consumer SSDs. Only a small number of original films are really left in the hands of SSD manufacturers, and the price is high. In addition, the price competition in the SSD market is so fierce, Cheap and large third-party packaging good die is naturally the first choice for manufacturers, and the consumer body is also very honest. According to the statistics of the domestic market, the SSD of manufacturers who can produce flash memory does not occupy a high share in the domestic market, and cheap channel manufacturers occupy most of the domestic market.

As for those inked die black chips, they basically won't appear on SSDs. They can't afford the number of reads and writes at the SSD level. However, they will still be found on cheap USB flash drives and memory cards.
