The era of AI is booming, and recently the US stock market's storage sector has been talked about every day, with NAND, DRAM, and HBM flying everywhere. Do you all know what they are? 😂 Here's a popular science post to boost your knowledge 1. NAND Pronounced /nænd/, roughly like "Nan-de" in Chinese. Full name NAND Flash, which is flash memory. Its main feature is that data is not lost when power is off, providing persistent storage. It's everywhere around us: SSD solid-state drives, USB drives, memory cards, the 256G or 1TB internal storage in phones—all of these use it. Large SSDs in enterprise servers also use NAND. SanDisk's core asset is NAND; AI datasets and vector databases ultimately rely on it. In short, it's used for storing data. 2. DRAM Pronounced /ˈdræm/, roughly like "Dram." Full name Dynamic Random Access Memory, which is the running memory. All data is cleared when power is off, but it's much faster than NAND. Corresponding products include computer RAM sticks, 12G/16G phone RAM, and server memory. Temporary data during GPU computations is stored in DRAM. In short, it's used for running processes; it doesn't store data long but runs fast. 3. HBM No need to memorize the pronunciation; just say the letters one by one. Full name High Bandwidth Memory, a high-end upgrade of DRAM. While regular DRAM chips are laid flat on the motherboard, HBM stacks multiple layers of chips vertically, maximizing bandwidth. High-end AI GPUs like Nvidia H100/H200 and AMD MI series come standard with HBM. Note that HBM is not a separate category; it is still part of the DRAM family, just a high-end form. Production mainly relies on three companies: Micron MU, Samsung, and SK Hynix. Finally, just remember roughly: NAND is for storage, DRAM is for running processes, and HBM is a special fast-running memory for AI. Is everything clear now? #AI 🦧 #USStockMarketKnowledge

RT @oceansbaby_: In various investment circles, the principle basically never changes~ If you look at this issue from a game theory perspective, you will find that, it is necessary to trap retail investors at the high point, which is beneficial to society as a whole. Only by trapping a large number of retail investors at the high point can they give up the illusion of financial freedom and be motivated to create diligently. 😂 https:/…

Everyone have a happy workday, Work 3 days and rest 7 days. After hardship comes sweetness, hehe✌️

Fortunately, I was busy these past two days and didn't have time to be on the chain, otherwise I definitely would have been involved in the giwa fake chain incident. It's fate; besides my own mistakes, I haven't suffered any major losses.

The moon on the 15th is rounder than on the 16th. Yesterday morning, I received Mid-Autumn mooncakes from @GMWalletHK and @KittanSex, super happy, and started eating them right away last night. The kids at home said the taste was delicious and especially liked the exquisite box for the mooncakes, haha, very thoughtful 🫡 Thanks to the bosses for their kindness, wishing GM all the best!

Have you seen people walking cats and dogs? Have you seen people walking ducks? 😂 Haha, so funny #LifeSnapshot

Riding on the recent low traffic, I'll first boost my followers a bit. Theoretically, everyone who comes to X has their own ideas: Some purely want to share, those who are good at sharing Some just ramble, people who like to vent and relax Of course, more are there to gain Elon’s appreciation and, along the way, earn some hard-earned money. Right? So which type are you? You need to figure this out to better find like-minded people.

I've been outside all day, It was pouring rain when I went out, and it was still raining when I came back. I have to go out again tomorrow, and there will be heavy rain tomorrow too. I don't want to go out, but I have to. There are still things to finish, and once this is done, I can happily enjoy the remaining vacation. In life, there are always one or two major things that must be taken care of, so they must be done well. Only by doing them well can you feel good, a once-and-for-all matter.🦧

As long as you put your heart into it, you can accomplish a lot, People say those who make money don't follow the rules, but I think it's more about finding the rules and successfully aligning with them~ It's like this: for an ordinary person, a loan is a liability; for a big shot, a loan is an investment—one is a burden, the other is wealth 🦧

President Trump, in less than ten minutes, posted five videos on 𝕏, going crazy, all with a 45° upward curl at the corners of his mouth 🦧

Congratulations to all the new original creators on 𝕏 who are earning their salaries, you guys are awesome! Truly top-notch. But why are the earnings so high, hundreds to thousands in a pile~ Turns out this is what a highly motivated day looks like.
