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...
In order to avoid losing data after power failure, there is exiting power failure protection mechanism in SSD. Based on the content of SDRAM, power failure protection mechanism can be divided into three main types. In addition, the quality of an SSD can be judged from its stability, performance and lifetime.
SSD firmware consists of mapping table, garbage collection, wear leveling and so on. The lifetime of NAND Flash is similar to the barrel principle, it’s necessary to balance the number of all blocks. The larger the OP, the faster the garbage collection and the smaller corresponding write amplification will be. So reading and writing performance becomes better, but the space the user can use will b...
The article introduces the comparison between HDD and SDD in terms of medium, performance and appearance. As we all know, Flash is divided into NAND Flash and NOR Flash. However, this article mainly tells us working principle of NAND Flash.
Insert micro SD card to expand additional storage space is a good choice to satisfy storage needs. The article gives some good advice to us for how to correctly select a micro SD card. Speed levels, application performance, brand reputation and user testing are important factors to be considered when purchasing micro SD cards.
This part mainly introduces characteristics of various memory such as CF card, MMD card, SM card, and so on. Besides, the author gives some idea about how to select proper memory according to you requirements. Application requirements will determine the type of memory, but some design parameters including the microcontroller, voltage range, battery life also need to be considered.
The memory is divided into several types by hierarchical structure, targeting at resolving the contradiction between speed and cost reasonably. In addition, the article also shows how SPI managers to manage the memory in detail.
Memory is a memory device in a computer system that stores programs and data according to the location specified by the controller. The article briefly introduces the concept, composition and classification of memory.
SSD Trim is used to solve the problem of hard disk speed slowing down, which is developed by Microsoft bands together with other SSD manufacturers. If SSD supports Trim command, it will keep pace for a long time. Otherwise, the longer it takes, the slower it will be.
The article introduces difference between memory and storage in mobile and computer in a way easy to understand. According to elucidating storage principles, we know that storage units of both DRAM and NAND are actually b instead of B. In addition, comparison among SLC, MLC and TLC is also shown here.
