About This Chart
The chart above provides a breakdown of Micron revenue by segment. Micron generated most of its sales from the Compute and Business unit in its Q3 FY18. Note that its DRAM and NAND products are sold in almost of its segments; the only difference is that the compute and business unit is geared more towards the computing space (personal PCs or servers) rather than embedded applications (such as RAM modules found in your car or refrigerator). But with that said, Micron has been able to grow its sales in all of its operating segments.
Micron Revenue By Segment Breakdown

The above section provides a breakdown of Micron Revenue By Segment. The section below provides a further segregation of its product segmentation.
Micron’s product portfolio of memory and storage solutions is based on their high-performance semiconductor memory and storage technologies, which include DRAM, NAND, 3D XPoint memory, and other technologies. They offer products in various forms, including wafers, components, and modules, as well as SSDs and multiple chip packages that combine their NAND with controllers and firmware.
DRAM: DRAM products are high-density, low-cost-per-bit, random access memory devices that provide high-speed data storage and retrieval with a variety of performance, pricing, and other characteristics. Sales of DRAM products were 64%, 58%, and 64% of their total net sales in 2017, 2016, and 2015, respectively.
Wafer, Component, and Module DRAM: DDR3 and DDR4 DRAM products offer high speed and bandwidth, primarily for use in computers, servers, networking devices, communications equipment, consumer electronics, automotive, and industrial applications. In 2017, we offered DDR4 and DDR3 products in 1Gb to 8Gb densities. Sales of DDR4 products increased significantly in 2017 and we expect further increases in 2018 as DDR4 DRAM replaces DDR3 DRAM products in many applications. Aggregate sales of DDR3 and DDR4 DRAM products were 40%, 31%, and 38% of their total net sales in 2017, 2016, and 2015, respectively.
LPDRAM products offer lower power consumption relative to other DRAM products and are used primarily in smartphones, tablets, automotive applications, laptop computers, and other mobile consumer devices that require low power consumption. Aggregate sales of their LPDDR4, LPDDR3, and other versions of LPDRAM products were 18% of their total net sales in each of 2017, 2016, and 2015.
Micron offers other DRAM products targeted to specialty markets, including DDR2 DRAM, DDR DRAM, GDDR5 and GDDR5X DRAM, SDRAM, and RLDRAM. These products are used in networking devices, servers, consumer electronics, communications equipment, computer peripherals, automotive and industrial applications, and computer memory upgrades.
Other DRAM: Micron offer HMC products, which are semiconductor memory devices where vertical stacks of DRAM die connected using through-silicon-via interconnects are placed above a small, high-speed logic layer.
NAND: NAND products are electrically re-writeable, non-volatile semiconductor memory and storage devices that retain content when power is turned off. NAND sales were 32%, 37%, and 33% of their total net sales in 2017, 2016, and 2015, respectively. NAND is ideal for mass-storage devices due to its fast erase and write times, high density, and low cost per bit relative to other solid-state memories. NAND-based storage devices are utilized in smartphones, SSDs, tablets, computers, automotive and industrial applications, networking, and other consumer applications. Removable storage devices, such as USB and Flash memory cards, are used with applications such as PCs, digital still cameras, and smartphones. The market for NAND products has grown rapidly and we expect it to continue to grow due to increased demand for these and other embedded and removable storage devices.
Wafer and Component NAND: Their NAND products feature a small cell structure that enables higher densities for demanding applications. Micron began selling commercial volumes of new products featuring their 3D NAND technology in 2016 and it composed 43% of their total Trade NAND sales in 2017. Micron expects 3D NAND sales to continue to increase in 2018. 3D NAND stacks layers of data storage cells vertically to create storage devices with higher capacity than competing planar NAND technologies. This enables more storage in a smaller space, bringing significant cost savings, low power usage and high performance to a range of mobile consumer devices as well as the most demanding enterprise deployments. Micron is currently in production of MLC and TLC versions of 3D NAND and, in 2017, TLC comprised a majority of their 3D NAND production. The significant majority of their 3D NAND products sold in 2017 featured 32 layers and we began ramping next generation 3D NAND products with 64 layers in 2017. Micron also offer high speed SLC, MLC, and TLC planar NAND products that are compatible with advanced interfaces in 1GB to 128GB densities.
SSDs: SSDs incorporate NAND, a controller, and firmware and are a significant portion of their net sales. Micron offers client, cloud, and enterprise SSDs which feature higher performance, reduced-power consumption, and enhanced reliability as compared to typical hard disk drives. Their client SSDs are targeted at notebooks, desktops, workstations, and other consumer applications. Increasingly their SSDs are being utilized in large-scale cloud environments. Using their 3D NAND process technology, their SSDs deliver read and write speeds that help improve boot and application load times and deliver higher performance than hard disk drives. Their client SSDs, including their newest line of 3D NAND SSDs, deliver world-class data storage, endurance, power efficiency, reliability, and performance for corporate users and are offered in SATA and PCIe NVMe solutions, with densities up to 2 terabytes, in 2.5-inch and M.2 form factors. Their enterprise SSDs are targeted at server and storage applications and incorporate their Extended Performance and Enhanced Reliability Technology (“XPERT”) architecture, which closely incorporates the storage and controller through highly optimized firmware algorithms and hardware enhancements. The end result is a set of market-focused enterprise features that deliver ultra-low latencies, improved data transfer time, power-loss protection, and cost-effectiveness, along with higher capacities and power efficiency. Micron offers enterprise SSDs with PCIe NVMe, SAS, and SATA interfaces, with capacities up to 3.2 terabytes.
Micron generally develops firmware and expect to introduce proprietary controllers into their SSDs in 2018, which will enable us to offer additional differentiated storage solutions for their customers. Sales of their client and cloud SSDs increased significantly in 2017, both in aggregate and as a percentage of their overall sales, and we expect this trend to continue over the next several years.
MCPs and Managed NAND: Micron offers MCP products that combine NAND with LPDRAM to enable small form-factor solutions that combine storage and execution memory. Micron also offers managed NAND products including e-MMC, UFS, and embedded USB. Their e-MMC products combine NAND with a logic controller that performs media management and Error Code Correction (“ECC”), which provides reduced ECC complexity, better system performance, improved reliability, easy integration, and lower overall system costs. Their e-MCP products combine e-MMC with LPDRAM on the same substrate, which improves overall functionality and performance while simplifying system design. MCP products are used in smartphone, automotive, industrial, and other consumer applications. Their MCP and managed NAND products generally feature proprietary firmware and leverage their expertise in NAND and DRAM technologies
3D XPoint Memory and Other:Micron introduced 3D XPoint technology, a new category of non-volatile memory, in 2015. 3D XPoint memory’s innovative, transistor-less, cross point architecture creates a three-dimensional checkerboard where memory cells sit at the intersection of word lines and bit lines, allowing the cells to be addressed individually. As a result, data can be written and read in small sizes, leading to fast and efficient read/write processes. Micron began producing 3D XPoint memory in 2016 and significantly increased production in 2017
Other NAND:Other products included primarily NOR Flash, which are electrically re-writeable semiconductor memory devices that offer fast read times and are used in automotive, industrial, connected home, and consumer applications.
