Author: Ning Nanshan Long press the QR code to join the storage technology and market group. Currently, China only has a presence in the small market of NOR Flash, which is a type of flash memory chip primarily used for storing code and some data. It is widely used in PC motherboards, security monitoring products, … Read more
NOR Flash technology is one of the two main types of non-volatile flash memory on the market today.Intel first developed NOR Flash technology in 1988, which completely changed the dominance of EPROM (Erasable Programmable Read-Only Memory) and EEPROM (Electrically Erasable Programmable Read-Only Memory).In 1989, Toshiba introduced the NAND Flash structure, emphasizing lower cost per bit, … Read more
This is an interesting comment that Little Lion saw in the background. This reader bought a generic SATA SSD from Xianyu, and after it dropped, he opened it up to find four SD cards assembled inside. Therefore, he asked, what is the difference between the two? Why can an SD card be used to impersonate … Read more
If you haven’t bought a storage card in a while, you might be surprised at the increasing number of various labels on today’s high-speed, large-capacity microSD and SD cards, which are becoming more and more difficult to understand.This is because, unlike in the past when they were only used for taking photos, storage cards are … Read more

As the application of SSDs in the market increases, the importance of SSDs as a core component of computer data storage is self-evident. Due to the rising prices of NAND Flash in 2016 and the first half of 2017, the prices of SSDs have also surged. According to the China Flash Market quotation, from Q2 … Read more
Today, we will introduce the two main characteristics of serial NAND Flash that prevent it from supporting XiP under the i.MXRT FlexSPI. In the embedded world, when we mention XiP devices (memory that supports code execution in place), the first thing that comes to mind should be NOR Flash. For example, mid-range and low-end MCUs … Read more
NAND Flash is a type of non-volatile random access storage medium based on the design of floating gate transistors. It uses floating gates to store charges, which can be retained even without power supply. There has been a previous explanation of the basic principles of NAND Flash technology, which can be referenced in the article … Read more
1.Definition and Uses of eMMC eMMC stands for “Embedded MultiMediaCard”, which is an embedded storage solution that integrates storage chips, controllers, and interfaces. It is commonly used in embedded systems, mobile devices, and other applications requiring compact, integrated storage. Here are some key features and uses of eMMC: 1.Integration: eMMC integrates storage chips, controllers, and … Read more
🟩Flash can be divided into two main categories: NOR Flash and NAND Flash. NAND has a large capacity and low cost per unit, while NOR has fast read speeds, high reliability, and quick erase speeds. NOR Flash is primarily used for coding applications, often related to computation; NAND Flash mainly functions as data storage, widely … Read more
