DXI (DRAMeXchange Index)

Q: DXI Purpose

A : The main purpose of the DXI index is to provide users with an easy to understand graphical representation of the DRAM industries market trend. The index is calculated by multiplying the mainstream DRAM chips with their respective spot price. The calculation is performed under a logical framework, providing users with a powerful tool in gaining a detailed insight of the market performance.

top

Q: Understanding the stock price changes through the DXI index

A : The DXI index not only reflects the output value of the DRAM industry, it also depicts the stock price changes of DRAM makers. According to statistical data compiled by DRAMeXchange on the stock price of relevant DRAM makers, such as Samsung, SK Hynix, Elpida, Micron, Nanya, Winbond...etc., a strong correlation is seen with the spot price. Therefore, the index provides users with an accurate account of the highly volatile memory business.

top

Q: Composition of the DXI

A : The DXI is a DRAM output value index, used to assist relevant DRAM specialists, analysts and fund managers to track the DRAM price and output trend. DRAMeXchange makes use of two important criteria in selecting the chips. First, the spot price of related chips must always be able to be maintained by DRAMeXchange. Second, the selected chips must reach our benchmark, and contribute over 60%-70% of the chosen DRAM makers output. Once the selected chips fail to meet the criteria, DRAMeXchange will renew its DXI calculation base.

Listed are the chips that comprise the DXI index for Nov. 2012

1.4 Calculation Base Period


A : DRAMeXchange collects the output data on a monthly basis. The August data is arbitrarily chosen to represent the output for Oct 1st. It is multiplied with the October chip price to serve as the calculation base period.

Price Information

Spot Price

Q: What is the definition of Spot Price?

A : Major spot market buyers and sellers are DRAM vendors, OEMs and system integrators (SI), channel distributors, module makers and brokers. Module makers' monthly revenues are about $5M to $300M. We cannot disclose detailed of company information due to protect the privacy of our clients.

top

Q : What is the Methodology of DRAMeXchange to update Spot Price?

A : Currently, DRAM manufacturers' monthly production volume is around 1000M(2Gb Equiv.), of which, about 10%-15% (100M-150M, 2Gb Equiv.) is supplied to the spot market which are mainly module makers, such as Kingston, Transcend, ADATA…etc; large-scale module makers deal with DRAM vendors directly in their price negotiations and product supplies. Due to necessary adjustments, a part of the process will be done through brokers, agents, distributors, forming a secondary market. Therefore, quotes from DRAMeXchange are mainly "secondary market"; prices will either be higher or lower than the direct quotes, depending on market conditions at the time.

The complex transaction network and exchange volumes involved in thousands of trading companies in the USA, Europe, and Asia makes it even more completed to make the estimates.

Also, with the efforts of DRAMeXchange's B2B department, spot price quotes for mainstream chips are based primarily on market transaction price; however, for spot price quotes for a small number of non-mainstream chips and the trading volume are usually small, we may use Bid/Ask prices as a reference in addition to market transaction price.

Contract Price

Q: What is the definition of Contract Price?

A : The current contract prices are settled prices agreed between buyers and sellers for a specific amount of shipment over a specific future timeframe. Most industry players set their contract price within a ranging from two weeks to a month. Contract prices we gathered exclude special deals that sellers negotiated with a limited group of strategic customer, or special agreement between buyers and sellers. Buyers and sellers in different industries:

Industry
Buyer
Seller
DRAM PC OEMs DRAM manufacturers
NAND Flash USB, Memory card markers NAND Flash manufacturers
Mobile DRAM Mobile device brands, vendors, agents Mobile DRAM manufacturers
eMMC Mobile device brands, vendors, agents eMMC manufacturers

top

Q: What is the Methodology of DRAMeXchange to update Contract Price?

A : DRAMeXchange conducts our estimate and assessment of current price via direct or indirect survey with associated companies, including manufacturers, distributors, agencies, OEMs, memory card markers…etc. With their outlook over the price trend, and our observation and verification on the market, DRAMeXchange provide a range for the contract price.

top

Q: How often does DRAMeXchange update the Contract price?

A : As the negotiation period and quote announcement is slightly different between each major vendor, DRAMeXchange in principle publishes the DRAM and NAND Flash current contract prices twice a month, and announces the Mobile DRAM and eMMC contract price quarterly.

DRAMeXchange Index, this index showing the DRAM output value changes, which is comprised of the output and price variations.

DRAM (please click HERE. to know more)

DRAM (Dynamic Random-access Memory) is a type of random-access memory that stores each bit of data in a separate capacitor with an integrated circuit. DRAM has varied types, such as FPM DRAM(Fast page mode DRAM), EDO DRAM(Extended data output), BEDO DRAM(Burst EDO DRAM), SDRAM(Synchronous DRAM), RDRAM(Rambus DRAM), DDR SDRAM(Double-data-rate SDRAM), DDR2 SDRAM(Double-data-rate 2 SDRAM), DDR3 SDRAM(Double-data-rate 3 SDRAM)

Due to different areas of application, DRAM products are separated into different types: PC DRAM, using on PC related products, such as Desktop, Notebook, Netbook, Ultrabook and some white brand tablet…etc Mobile DRAM, using on Mobile devices, such as feature phone, smartphone and tablet…etc Server DRAM, using on Server applications, such as workstations, servers…etc Graphic DRAM, products are included DDR and GDDR, and are designed for graphics application Consumer/Specialty DRAM, products are designed for consumer devices, such as TV, navigation devices, digital/video camera…etc

NAND Flash (please click HERE. to know more)

Flash memory is an electronic non-volatile computer storage device that can be electrically erased and reprogrammed. There are two main types of flash memory, which are named after the NAND and NOR logic gates. NAND Flash is primarily used in main memory, memory cards, USB flash drives, SSD and similar products, for general storage and transfer of data. NAND Flash memory stores information in an array of memory cells made from floating-gate transistors, and generally has 3 types:
SLC(Single-level cell): each cell stores only one bit of information
MLC(multi-level cell, 2 bit MLC): each cell stores more than a single bit of information. Using multiple levels per cell to allow more bits to be stored using the same number of transistors
TLC(Triple-level cell, 3 bit MLC): each cell stores more than a single bit of information. The performance, endurance and data retention of 3 bit MLC are inferior to 2 bit MLC, and it could be used on low to middle-class memory cards, USB flash drives and MP3 players.

Memory Card

Memory card or flash card is an electronic flash memory data storage device used for storing digital information. They are commonly used in many electronic devices, such as digital cameras, mobile phones, MP3 players and video game consoles.

eMMC

eMMC is an embedded non-volatile memory system, comprised of both NAND Flash and a NAND Flash controller on the same silicon die.

SSD

Solid-State Drive(SSD) is a data storage device using integrated circuit assemblies as memory to store data persistently. Most SSDs use NAND Flash memory to retains data without power, and compared with floppy disks or traditional electromechanical magnetic disks(such as HDDs), SSDs are typically less susceptible to physical shock, much quieter, have lower access time, and less latency.
