Chapter 232 (1/2)

Compared with the electronic compass that can be delivered directly, Saito benwu cares about two other things: audio chip and gravity accelerometer.

Although it is a giant in Japan's semiconductor industry, Asahi's audio chip does not occupy the world because of the existence of a stronger Italian French semiconductor company.

Even if Saito benwu believes that the audio chips produced by his company have reached the world-class level, the sales volume of Asahi Kasei's audio chips has not been very good because of the long-term monopoly of Italy France semiconductor.

There are also gravity accelerometers. Apple once asked Asahi Huacheng, but Asahi Huacheng finally lost. They don't know who they lost to.

The so-called gravity accelerometer is a small metal kit built into the machine. Because there are three axes to maintain balance, this tora type metal accelerometer will remain horizontal and vertical at any time.

The gravity accelerometer can automatically sense the change of mechanical orientation, so as to adjust and switch the function of corresponding change.

Saito benwu knows that at present, Apple has used the gravity accelerometer on the mobile phone they developed. It is said that it can automatically correct the screen according to the handheld direction. The use of this novel smart phone makes Saito benwu very interested. Although the effect of previous research and development was not very good, it has made great progress.

Saito benwu even believed that if he had another competition, his gravity accelerator would never lose to others.

Now it seems that there is always a way out of heaven.

Although Apple's orders are gone, the materials and design drawings brought by this Chinese teenager are highly professional and very in line with the characteristics of Asahi Huacheng microelectronics. Naturally, Saito benwu is interested.

The Japanese are much more careful than the Americans. Therefore, even though Saito benwu has been moved, he politely asked Xiao Qi to leave the design drawings and schemes for discussion with the researchers.

Of course, the necessary confidentiality agreement was signed in the presence of two staff members of Citibank. Xiao Qi was not very confident about the Japanese's reputation for the Chinese people.

Saito benwu should consider.

Bilda's DRAM memory chip and Toshiba's NAND flash memory chip don't pay so much attention. Because the technology is mature and won't be modified, they let Xiao Qi purchase directly.

The difference between the two is actually very simple. DRAM memory chip has fast real-time storage speed, but the data will disappear after power failure. This memory chip is usually used to play games and use working software; NAND flash memory chip is stored for a long time and will not disappear after power failure. It is usually used on mobile phone memory card.

To put it bluntly, DRAM memory chip is equivalent to the memory of ordinary computer, and NAND flash memory chip is equivalent to the hard disk of ordinary computer.

Memory and hard disk.

It's that simple.
