All of Micron, SK Hynix and YMTC announced their new generation three-dimensional flash solution in CMFS 2018. There are three advantages including enhancing memory density, cutting costs and reducing manufacturing cycle. Micron releases the world’s first QLC SSD of 5210 ION series and it is used as enterprise-class storage.
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 int...
The article mainly talks about how to change a flash memory chip into an USB in a relatively simple way. Though making a USB by yourself isn’t always cheaper than purchasing, but you can feel the joy of DIY.
The mechanical hard disk work is achieved by mechanically, while solid state hard drive is pure chip structure without mechanical parts, and they have great difference in overall performance. In terms of reading and writing speed, SSD has higher speed than HDD because of its chip-based flash access mode. And SSD is called the new power of the hard disk industry with its superior performance.
The hard disk market has been monopolized by several major storage manufacturers in Japan, Korea and United States. However, domestic storage manufacturers represented by YMTC is catching up. Although SSD from SLC to QLC has much shortcoming in erasure times, improvement in capacity allow QLC SSD to catch up with HDD, perhaps achieving SSD $0.14 per GB.
SSD interface continues to evolve with PCIe scalability better than SATA so than client PCIe SSD is expected to reach a market share of about 50% by 2018. But it’s a question how to save costs to reduce the price. This article mainly suggests that DRAM-Less SSD improves overall performance improvement by introducing HMB.
TLC is a flash memory that can store 3 pieces of information per unit. TLC has the lowest comprehensive performance and the cheapest price but the performance of it can be improved by other methods. It needs 8 kinds of voltage states to save more data.
This article mainly introduces what is 3D NAND flash memory and its advantage. 3D NAND is a new type of flash memory, which can solve the limitation caused by 2D or flat flash memory, but there is still a long way to go. Many manufactures are working hard to achieve stacking 140 layers, which means a huge advantage to compete with other products.
The article introduce that there is a performance differences of the memory cards at different class or even same class by testing the performance of Class 10 products under USB 2.0 and USB 3.0 interfaces. Different classes are suitable for different consumers. Performance, capacity and price should be considered when choosing them. In addition, UHS-1 products can provide more performance for user...
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.
