Prevent being fooled in photography: How many “tricks” does a memory card have in the hands of a merchant?(2)
2019-07-14

Any photographer will be confused by the technical terms and parameters on the camera memory card. Only when we know more about some basic elements of the camera memory card, can we choose the camera memory card correctly, so as to meet our demand for the capacity and speed of the camera. This article will guide you to choose the storage card wisely from four aspects: the format, speed, capacity and price of the camera storage card. At the same time, it will prevent you from being cheated when purchasing.

What is on earth the difference between NAND Flash and NOR Flash? (1)
2019-07-11

NOR flash memory is an ideal choice for applications that require lower capacity, faster random read access, and higher data reliability. For example, what code execution requires. NAND flash memory is ideal for applications that require higher memory capacity and faster write and erase operations, such as data storage and so on.

USB Type-C Specification and Analysis of Authentication Solution
2019-07-10

Released in August 2014, the USB Type-C specification has four features of smaller size, power charging, extensibility and usability. The article also lists several effective authentication solutions. In the follow-up development, USB Type- C aims to launch a next-generation USB interface specification generations and replace all existing USB 2.0 Micro-B connectors.

Difference between USB 2.0 and USB 3.0
2019-07-8

The passage mainly introduces the difference between USB 2.0 and USB 3.0. In addition to theoretical maximum transmission speed and maximum current supply capacity, you can easily distinguish them from their appearance and structure such as the color of base and the number of contracts.

Western Digital develops zoned SSD to improve data access speed
2019-06-28

Shingled drives are to store PBs of read-centric bulk data as cost effectively as possible. Western Digital is developing zoned SSDs in order to speed data access and prolong the life of the drivers by making write amplification factor as low as practicable. Therefore, for this purpose, Western Digital believes that applications that use shingled disk drives could instead use zoned SSDs with few code changes.

Why does speed drop happen in TLC/QLC SSD?(end)
2019-05-27

The upgrading of flash type from SLC to MLC, TLC and QLC results in a significant decline in performance, especially in write performance, due to more charge bits to save in every cell and increasing capacity. Garbage collection and TRIM can also affect performance reduction. But now, performance reduction caused by garbage collection and TRIM is much less. In addition, the more space solid state drive uses, the less they have left. It is detrimental to cache acceleration, resulting in bad performance. If you mind about speed drop, you have better choose MLC solid state drive or no less than 1TB solid state drive.

Why does speed drop happen in TLC/QLC SSD? (1)
2019-05-26

Although solid state drive is popular in our daily life, it still has a disgusting problem, namely, declining performance. Experienced users should have experience it, while some people actually do not realize this problem. Let us talk about declining performance of solid state drive in this paper.

We can trust the quality of QLC SSD?
2019-05-05

QLC SSD is the latest product to meet the demands of high capacity and low cost. It is the developing trend of SSD industry, although people have doubts and distrusts on it, it will prove its performance at the end. Finally the new technology will replace the old one, as if we take time to wait and test. It is the good sign of NAND flash market, no matter SSD or Micro SD Card; they will have more new solutions in future.

Learn about every aspect of photoresist (3)
2019-03-30

This part introduces the evolution of photoresist from exposure source to film-forming material in detail. As time goes by, four types of photoresist have been developed by shrinking the line width of integrated circuits and continuously improving resolution, in order to meet various requirements.

Price of DRAM falls again, setting a record in recent nine years.
2019-03-17

According to latest survey of DRAMeXchange, DRAM prices will continue to decline due to oversupply and weak demand. At present, most of market share of memory are mastered by three large companies, namely Samsung, SK Hynix and Micron. The speed of decreasing or increasing production is different, easy to cause legal problem of monopoly. Fortunately, it is generally believed that market conditions will recover with increasing demand in the second half of the year.

Differences among DRAM, SDRAM, and SRAM
2019-2-6
The article mainly introduces differences among DRAM, SDRAM, and SRAM in detail. DRAM requires refreshing with large capacity, while SDRAM and SRAM not. In addition, the storage unit structure of them also be compared in the passage.
A brief introduction to the development of DDR memory
2019-01-14

The article briefly introduces the development of memory DDR. Memory can be divided into RAM and ROM according to whether data is lost or not at power failure. In addition, RAM can further be divided into SRAM and DRAM. The development of SDRAM is from 30pin SIPP interface to 30pin SIMM or 72pin SIMM. It also briefly show the characters and application of asynchronous DRAM which can be divided into FPM DRAM and EDO DRAM. From DDR to DDR4, the data transmission rate is increasing and capacity is becoming larger and larger.

What is mobile ram? What’s the meanning of ram?
2019-01-07

Mobile RAM RAM falls into SRAM and DRAM, which decides the speed of mobile system and running program. It’s features include random access, volitality, high accessing speed, need of refreshment and sensitive to static electricity.
