What is the Chinese meaning of DRAM memory?

The Chinese meaning of DRAM memory is dynamic random access memory.

Random access memory (RAM) is divided into static random access memory and dynamic random access memory. Static random access memory: fast read and write speed, high production cost, mostly used for cache memory with small capacity. Dynamic random access memory: slow in reading and writing speed, highly integrated, and mostly used for main memory with larger capacity.

Introduction to DRAM:

Dynamic Random Access Memory (DRAM) is a semiconductor memory. Its main principle is to use capacitors to store charges. The number of bits represents whether a binary bit (bit) is 1 or 0. Since transistors have leakage current in reality, the amount of charge stored on the capacitor is not enough to correctly identify the data, resulting in data corruption.

Therefore, periodic charging is an unavoidable requirement for DRAM. Because of this characteristic that requires periodic refresh, it is called "dynamic" memory. Relatively speaking, as long as static memory (SRAM) stores data, the memory will not be lost even if it is not refreshed.

Compared with SRAM, the advantage of DRAM is its simple structure - each bit of data only needs one capacitor and one transistor to process, compared to SRAM, which usually requires six transistors per bit. For this reason, DRAM has a very high density, a high capacity per unit volume and therefore a low cost. But on the contrary, DRAM also has the disadvantages of slow access speed and high power consumption.

Like most random access memories (RAM), DRAM is a volatile memory device because the data stored in it will disappear soon after the power is cut off.

The DRAM light on the motherboard is orange but there is no display The DRAM light on the motherboard is orange but there is no display Feb 19, 2024 am 11:09 AM

This article will explore the role of the DRAM indicator on the motherboard. When the DRAM light on the motherboard shows orange but nothing is displayed, it may mean that there is some hardware issue. In this case, this article will provide some suggestions to solve these problems. The DRAM indicator on the motherboard is orange but does not show that the motherboard is the core hardware of the computer and connects other hardware components such as the CPU, RAM and hard drive. When there is a hardware problem, the motherboard will sound an alarm or display the problem through LED indicators. If the DRAM indicator light is orange but there is no display, you can try the following suggestions. Perform a hard reset to clear CMOS. Reseat your memory modules and check each memory module. Refresh your BIOS. The problem may be with your memory or CPU. Get professional support.

1c nano generation memory competition: Samsung plans to increase the use of EUV, Micron will introduce molybdenum and ruthenium materials 1c nano generation memory competition: Samsung plans to increase the use of EUV, Micron will introduce molybdenum and ruthenium materials Feb 04, 2024 am 09:40 AM

Korean media TheElec reported that Samsung and Micron will introduce more new technologies in the next generation of DRAM memory, the 1cnm process. This move is expected to further improve memory performance and energy efficiency. As the main leaders in the global DRAM market, Samsung and Micron's technological innovation will promote the development of the entire industry. This also means that future memory products will be more efficient and powerful. Note from this site: The 1cnm generation is the sixth 10+nm generation, and Micron also calls it the 1γnm process. The most advanced memory currently is the 1bnm generation, and Samsung calls 1bnm a 12nm-level process. ChoiJeong-dong, senior vice president of analyst firm TechInsights, said at a recent seminar that Micron will be at the 1cnm Festival

Sources say SK Hynix's five-layer stacked 3D DRAM memory yield has reached 56.1% Sources say SK Hynix's five-layer stacked 3D DRAM memory yield has reached 56.1% Jun 24, 2024 pm 01:52 PM

According to news from this website on June 24, Korean media BusinessKorea reported that industry insiders revealed that SK Hynix published the latest research paper on 3D DRAM technology at the VLSI 2024 Summit held in Hawaii, USA from June 16 to 20. In this paper, SK Hynix reports that its five-layer stacked 3D DRAM memory yield has reached 56.1%, and the 3D DRAM in the experiment exhibits similar characteristics to current 2D DRAM. According to reports, unlike traditional DRAM, which arranges memory cells horizontally, 3D DRAM stacks cells vertically to achieve higher density in the same space. However, SK hynix

What should I do if the dram light keeps on and the phone cannot be turned on? What should I do if the dram light keeps on and the phone cannot be turned on? May 15, 2023 pm 05:15 PM

Solution to the problem that the DRAM light is always on and cannot be turned on: 1. Check whether the memory module is correctly installed in the memory slot, insert the memory into the slot and make sure it is firmly fixed in place; 2. Use compressed gas or a soft brush to clean the memory slot to ensure that there is no dust or impurities affecting the memory module's contact; 3. Check whether the memory module is damaged or not working properly, choose a memory module that is compatible with the motherboard to replace, and ensure that the specifications, capacity and speed of the memory module are consistent with the requirements of the motherboard. ; 4. Re-insert and unplug the memory module to make sure the memory module is in good contact; 5. Replace the motherboard.
