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.
The comparison between different memories shows the advantage of memristor in integration density and reading and writing time.
Memory can be divide into bare bar and the bar wearing cooling fin in appearance. Generally speaking, most of dressed up bars are OC strips with a higher frequency when the XMP option is turned on, and bare bar has a low frequency.
DRAM is the abbreviation of Dynamic random access memory, it’s power dissipation is lower than SRAM.
In flash memory, when the time of data storage reaches a certain value, it will be wrong because of the TAT effect. However, the Read Scrub technology of SSDs will reduce the error that ECC can't correct, so as to solve the problem of data retention. And there are also some data integrity techniques to ensure data integrity.
