What is iNAND? What are the advantages of iNAND?

Users can completely default that they are SD cards or MMC cards. Compared with MLC, iNAND has the following advantages: 1, improving performance 1) reducing the workload of SOC and saving SOC resources. If MLC is used as storage, SOC will participate in the bad block management and ECC error correction of flash memory, which will sacrifice some SOC performance. If Innd is used, the management of FLASH will be completed by Innd, and SOC will only read and write Innd when necessary, and it is completely unnecessary to pay attention to Innd at other times. 2) Fast reading and writing speed (1)iNAND has a built-in cache module, which can help users to increase the speed to about 10 times that of MLC if they want to store small-capacity files. The cache module does not need user control, so as long as small-capacity files are stored, the cache will start automatically, which is very convenient. (2)iNAND can simulate the built-in MLC FLASH as SLC, so that iNAND has the performance of SLC's reading and writing speed, thus improving the reading and writing speed. 3) The product is more reliable and stable. The iNAND patented by Sandisk, built-in power-off protection, wear leveling and other technologies can help customers improve the reading and writing life of FLASH, prevent the system from being damaged by sudden power failure, and reduce the repair rate of products. 2. Reduce the cost of the system First of all, iNAND has a certain price advantage because the FLASH selected by iNANDZ is generally the latest and most advanced FLASH on the market. Secondly, iInD packages with different capacities are consistent. If a customer has several models with different capacities, then only one set of PCB is needed, which can help customers simplify their work and improve efficiency. For example, Apple iPHONE has 8G, 16G capacity products, and his PCB only needs one set, so it can be labeled with the appropriate iInD during production. 3. It is convenient to buy at home and abroad. Only pay attention to the capacity used, and do not need to control the process and architecture. Many CPUs are not completely compatible with ordinary NAND FLASH. If a CPU supports FLASH with 5 1nm technology at most, if the products of FLASH manufacturers are upgraded, customers may encounter procurement difficulties and other problems. There are also products of Samsung, Hyundai and Micron in the market. They all meet the standards of JEDEC Committee and the products are completely compatible. 4, simple and easy to use, speed up your product development progress 1) For software engineers, when the FLASH process changes, its corresponding driver needs to be changed, and its program transplantation and code upgrade need to be debugged again, while iNAND's product driver is exactly the same, so there is no worries after a successful debugging;
