What is DRAM
DRAM products are high-density, low-cost-per-bit, RAM, (or random access memory) devices that provide high-speed data storage and retrieval. Micron Technology, Inc.’s (MU) standard DRAM products include DDR4, DDR3, and DDR2. These are standardized, high-density, high-volume products for use in computers and servers as main memory systems. They are preferred products because they offer high speed and high bandwidth at a comparatively low cost. DDR3 and DDR2 products contributed 31% and 7% towards total revenues in 2013.
Micron’s DRAM specialty memory products include the following:
- LPDRAM, or low power DRAM – These DRAM products consume less power. For this reason, they are used in laptops, tablets, and other consumer devices.
- RLDRAM, or reduced latency DRAM – These products are used in low-profile memory modules.
- PSRAM, or pseudo-static DRAM – These products are used in mobile devices.
Micron’s specialty DRAM products cater to networking devices, servers, consumer electronics, communications equipment, computer peripherals, and computer memory up-gradation space. Specialty DRAM products contributed 10% towards the company’s overall revenues in 2013.
DRAM revenues are rising with each fiscal quarter
In 4Q2014, DRAM contributed 68% to Micron’s overall revenues. As the chart above shows, DRAM’s contribution to overall revenues is increasing on a year-over-year basis. Its contribution towards FY14 revenues had not been reported at the time of publication.
Hybrid memory cube: A collaborative effort
HMC, or hybrid memory cube, is a new memory architecture that enables ultra-high system performance with significantly lower-cost per bit. Its development was led by eight of the industry’s leading companies—Altera, ARM, International Business Machines Corp. (IBM), SK Hynix, Micron, Open-Silicon, Samsung Electronics Co Ltd (SSNLF), and Xilinx. Micron began testing HMC in September 2013.

End markets and customers
Mobile, computing and PC, and server markets contributed 30%, 40%, and 15%, respectively, towards DRAM business in FY14. Its key customers include Intel Corporation (INTC) and Hewlett-Packard Company (HPQ). Each of these contributed 10% towards Micron’s overall revenues.
