Micron makes semiconductor memory and storage products. The practical distinction is that DRAM is temporary working memory for active computing, while NAND is persistent storage used in products such as SSDs. High-bandwidth memory (HBM) is a specialized, stacked form of DRAM designed to move data quickly between memory and processors in demanding AI and high-performance computing systems.
What does Micron make?
Micron Technology makes memory and storage components and products for data centers, personal computers, mobile devices, automotive systems, industrial equipment, and other embedded applications. Its portfolio includes DRAM components and modules, NAND products, SSDs, managed NAND, HBM, multichip packages, and wafers. Some of its system-level storage products combine NAND with a controller and firmware, and may also include DRAM.
That range matters: Micron does not only sell loose memory chips. Its products can be components used by other manufacturers or more complete products, such as memory modules and SSDs.
What is the difference between DRAM and NAND?
| Technology | What it does | Key distinction | Examples of uses Micron identifies |
|---|---|---|---|
| DRAM | Provides working memory for active tasks and computation | Volatile: it loses its contents when power is off | Data center, client PC, graphics, industrial, mobile, and automotive |
| NAND | Stores data persistently, commonly in SSDs and managed flash products | Nonvolatile and rewritable | Data center, client PC, consumer, automotive, mobile, and embedded applications |
In everyday terms, DRAM holds the information a system is actively using; NAND keeps files and other data for later. They are not interchangeable: one is temporary working memory, and the other is persistent storage. Micron’s company filing describes both product types and the markets they serve.

What is HBM, and how does it differ from regular DRAM?
HBM stands for High Bandwidth Memory. It is DRAM, not NAND, built by stacking memory dies vertically and connecting them with through-silicon vias (TSVs). This architecture is intended to provide high data bandwidth and close integration with processors, making HBM useful in AI and high-performance computing systems.
Micron’s HBM4 FAQ explains that conventional DRAM such as DDR handles general computing tasks, while HBM supports AI and HPC workloads that need continuous streams of data. This is a vendor-authored explanation, not an independent industry standard definition.
Rank #2
- Requires overclocking/BIOS adjustments. Maximum speed and performance depends on system components, including motherboard and CPU.
- G.SKILL Flare X5 Series DDR5 U-DIMM Memory Kit, Model: F5-6000J3636F16GX2-FX5
- Non-ECC, DDR5 U-DIMM, 288-pin, for Desktop PC & Gaming
- Includes JEDEC default profile, and AMD EXPO & Intel XMP 3.0 memory overclock profile
- Do not mix memory kits. Memory kits are sold in matched kits that are designed to run together as a set. Mixing memory kits will result in stability issues or system failure.
HBM complements rather than replaces all other system memory. Micron describes HBM working alongside DDR5 or LPDDR5: HBM serves bandwidth-intensive workloads near the processor, while conventional DRAM continues to support broader system tasks. HBM is not a standard DDR5 memory module or a consumer DIMM replacement.
What does Micron’s HBM4 product offer?
Micron’s HBM4 product page reports that its HBM4 36GB 12-high stack is in high-volume production and is designed for next-generation AI platforms. Micron lists a 2048-pin interface, pin speeds greater than 11.0 Gbps, and bandwidth greater than 2.8 TB/s per stack.

These are Micron-reported product specifications, not independently verified market-wide measurements. The bandwidth and comparative efficiency context on Micron’s page is for 12-high HBM4 versus 12-high HBM3E; Micron describes its efficiency comparison against HBM3E 12-high at similar speeds. The figures should not be generalized to every HBM configuration or generation.
How do Micron’s products fit into a computer or device?
In servers and data centers
Micron lists DRAM modules for servers, workstations, and data centers, alongside data-center SSDs. In AI systems, HBM can sit close to processors to provide high-bandwidth access for demanding workloads; it works alongside conventional system memory rather than serving as a universal substitute for it.

In PCs and consumer devices
Micron makes DRAM components and modules for client PCs, and NAND-based SSDs for client devices. DDR5 RAM is one example of DRAM: it provides temporary working memory, and it must match a system’s supported memory type and configuration. An SSD, by contrast, provides persistent storage.
In mobile, automotive, and embedded systems
Micron identifies DRAM and NAND uses across mobile and automotive markets, with NAND also serving consumer and embedded applications. Its fiscal 2026 results page cites LPDDR5X shipments for flagship mobile devices and SSD shipments for KV-cache applications as examples of activity beyond HBM.

Start with the job the product needs to do rather than comparing the names as if they were competing versions of the same thing.
- Choose by function: DRAM supports active computation; NAND stores data persistently; HBM is a high-bandwidth form of DRAM for tightly coupled compute systems.
- Check system fit: For a PC memory module, compatibility with the system matters. HBM is a processor-integrated architecture, not a drop-in DIMM.
- Compare relevant specifications: Depending on the role, capacity, bandwidth or latency, power, and physical or package integration may matter. For HBM generation comparisons, account for stack height and capacity as well as bandwidth.
- Match the workload: General computing and persistent file storage have different needs from AI or HPC workloads that move large volumes of data to processors.
Micron’s portfolio spans all three categories: temporary DRAM, persistent NAND storage, and HBM for bandwidth-intensive compute. Its product descriptions and specifications are company claims; they should be read in that context.
