For Chinese characters, what encoding is used to save the information in memory or disk?
For Chinese characters, "GB2312-80" encoding is used to store and transmit information in memory or disk. GB2312-80 refers to the Chinese character encoding character set for information exchange. GB2312 encoding is suitable for information exchange between Chinese character processing, Chinese character communication and other systems. It is popular in mainland China; Singapore and other places also use this encoding.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

GB2312-80 Chinese character internal code
"Chinese Character Coded Character Set for Information Exchange" was released by the State Administration of Standards of China in 1980, on May 1, 1981 A set of national standards that have been implemented, the standard number is GB 2312-1980.
GB2312 encoding is suitable for information exchange between Chinese character processing, Chinese character communication and other systems. It is popular in mainland China; Singapore and other places also use this encoding. Almost all Chinese systems and international software in mainland China support GB 2312.
The basic set includes a total of 6763 Chinese characters and 682 non-Chinese graphic characters. The entire character set is divided into 94 areas, each area has 94 bits. There is only one character in each location, so the location and location can be used to encode Chinese characters, which is called location code.
Add 2020H to the location code converted into hexadecimal to get the national standard code. Add the national standard code to 8080H to get the commonly used computer internal code. In 1995, the "Chinese Character Coding Extension Specification" (GBK) was promulgated. GBK is compatible with the internal code standard corresponding to the GB 2312-1980 national standard. At the same time, it supports all Chinese, Japanese, and Korean (CJK) Chinese characters of ISO/IEC10646-1 and GB 13000-1 at the vocabulary level, a total of 20,902 characters.

Convert VirtualBox fixed disk to dynamic disk and vice versa
Mar 25, 2024 am 09:36 AM
When creating a virtual machine, you will be asked to select a disk type, you can select fixed disk or dynamic disk. What if you choose fixed disks and later realize you need dynamic disks, or vice versa? Good! You can convert one to the other. In this post, we will see how to convert VirtualBox fixed disk to dynamic disk and vice versa. A dynamic disk is a virtual hard disk that initially has a small size and grows in size as you store data in the virtual machine. Dynamic disks are very efficient at saving storage space because they only take up as much host storage space as needed. However, as disk capacity expands, your computer's performance may be slightly affected. Fixed disks and dynamic disks are commonly used in virtual machines
Is there a big difference between 8g and 16g memory in computers? (Choose 8g or 16g of computer memory)
Mar 13, 2024 pm 06:10 PM
When novice users buy a computer, they will be curious about the difference between 8g and 16g computer memory? Should I choose 8g or 16g? In response to this problem, today the editor will explain it to you in detail. Is there a big difference between 8g and 16g of computer memory? 1. For ordinary families or ordinary work, 8G running memory can meet the requirements, so there is not much difference between 8g and 16g during use. 2. When used by game enthusiasts, currently large-scale games basically start at 6g, and 8g is the minimum standard. Currently, when the screen is 2k, higher resolution will not bring higher frame rate performance, so there is no big difference between 8g and 16g. 3. For audio and video editing users, there will be obvious differences between 8g and 16g.
Sources say Samsung Electronics and SK Hynix will commercialize stacked mobile memory after 2026
Sep 03, 2024 pm 02:15 PM
According to news from this website on September 3, Korean media etnews reported yesterday (local time) that Samsung Electronics and SK Hynix’s “HBM-like” stacked structure mobile memory products will be commercialized after 2026. Sources said that the two Korean memory giants regard stacked mobile memory as an important source of future revenue and plan to expand "HBM-like memory" to smartphones, tablets and laptops to provide power for end-side AI. According to previous reports on this site, Samsung Electronics’ product is called LPWide I/O memory, and SK Hynix calls this technology VFO. The two companies have used roughly the same technical route, which is to combine fan-out packaging and vertical channels. Samsung Electronics’ LPWide I/O memory has a bit width of 512
Samsung announced the completion of 16-layer hybrid bonding stacking process technology verification, which is expected to be widely used in HBM4 memory
Apr 07, 2024 pm 09:19 PM
According to the report, Samsung Electronics executive Dae Woo Kim said that at the 2024 Korean Microelectronics and Packaging Society Annual Meeting, Samsung Electronics will complete the verification of the 16-layer hybrid bonding HBM memory technology. It is reported that this technology has passed technical verification. The report also stated that this technical verification will lay the foundation for the development of the memory market in the next few years. DaeWooKim said that Samsung Electronics has successfully manufactured a 16-layer stacked HBM3 memory based on hybrid bonding technology. The memory sample works normally. In the future, the 16-layer stacked hybrid bonding technology will be used for mass production of HBM4 memory. ▲Image source TheElec, same as below. Compared with the existing bonding process, hybrid bonding does not need to add bumps between DRAM memory layers, but directly connects the upper and lower layers copper to copper.
Micron: HBM memory consumes 3 times the wafer volume, and production capacity is basically booked for next year
Mar 22, 2024 pm 08:16 PM
This site reported on March 21 that Micron held a conference call after releasing its quarterly financial report. At the conference, Micron CEO Sanjay Mehrotra said that compared to traditional memory, HBM consumes significantly more wafers. Micron said that when producing the same capacity at the same node, the current most advanced HBM3E memory consumes three times more wafers than standard DDR5, and it is expected that as performance improves and packaging complexity intensifies, in the future HBM4 This ratio will further increase. Referring to previous reports on this site, this high ratio is partly due to HBM’s low yield rate. HBM memory is stacked with multi-layer DRAM memory TSV connections. A problem with one layer means that the entire
