Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory are named after the NAND and NOR logic gates. The individual flash memory cells, consisting of floating-gate MOSFETs , exhibit internal characteristics similar to those of the corresponding gates.A flash memory device typically consists of one or more flash memory chips (each holding many flash memory cells) along with a separate flash memory controller chip.
NAND flash memory is a type of nonvolatile storage technology that does not require power to retain data. An important goal of NAND flash development has been to reduce the cost per bit and to increase maximum chip capacity so that flash memory can compete with magnetic storage devices, such as hard disks. NAND flash has found a market in devices to which large files are frequently uploaded and replaced. MP3 players, digital cameras and USB flash drives use NAND technology.▶ Voir plus
NOR flash memory is one of two types of nonvolatile storage technologies. Nonvolatile memory does not require power to retain data.NOR and NAND use different logic gates -- the fundamental building block of digital circuits -- in each memory cell to map data.▶ Voir plus
eMMC is the abbreviation of Embedded MultiMedia Card, is easy to use as embedded multimedia card (MMC) memory . eMMC encapsulates a integration of a controller, provides a standard interface and memory management, make the mobile makers will be able to focus on theire energy to develp the other parts and shorten the time for the product to be launched into the market.▶ Voir plus
Dynamic random-access memory (DRAM) is a type of random access semiconductor memory that stores each bit of data in a memory cell consisting of a tiny capacitor and a transistor, both typically based on metal-oxide-semiconductor (MOS) technology.DRAM typically takes the form of an integrated circuit chip, which can consist of dozens to billions of DRAM memory cells. DRAM chips are widely used in digital electronics where low-cost and high-capacity computer memory is required. One of the largest applications for DRAM is the main memory in modern computers and graphics cards.

GDDR （Graphics Double Data Rate）SDRAM ，is one of the key core components on the video card , Its advantages and disadvantages & capacity will be directly related to the performance of the video card. it's family have GDDR, GDDR2, GDDR3,GDDR4 andGDDR5.▶ Voir plus
SDRAM is the abbreviation of Dynamic Random Access Memory . is the most common system memory.It can read and write at any time, and very fast. usually as an operating system or other running program 's temporary data storage medium.▶ Voir plus
Memory giant winbond has claimed the top spot as the world's largest supplier of NOR Flash last year, Taiwan business times reported.According to the latest market data of WebFeet Research, winbond's sales volume of NOR Flash memory last year accounted for 22.8% of the global market, which was attributed to the steady shipments. Winbond's total shipments of Flash memory last year exceeded 3 billion, accounting for 27.3% of the global shipments of NOR Flash memory productsApprendre encore plus >

South Korea now has the highest number of new cases of coronary pneumonia outside China, due to a sudden surge in confirmed cases.Following SK hynix's announcement last week of an emergency quarantine of 800 people, samsung electronics also reported confirmed cases, with some analysts saying the outbreak, if not controlled, could hit the global semiconductor supply chain...Apprendre encore plus >
As early as Dec. 31, 2019, after a power outage at samsung's Line 13 plant in hwaseong, South Korea, led to production disruptions, there were concerns about the impact of such outages on the broader DRAM market.But the industry seems to have completely ignored the incident.Samsung's outage won't have a significant impact on commodity DRAM prices, according to analysts at TrendForce DRAMeXchange.Overall, though, DDR4 prices are still gradually rising as part of cyclical market volatilityApprendre encore plus >
