Previously, I provided a detailed introduction to the history of HDDs, floppy disks, and CDs. You may have noticed that in our daily lives, there are actually many more storage media than the three mentioned above. The USB drives, TF cards, SD cards we frequently use, as well as the DDR memory and SSDs used … Read more
Click the above Computer Enthusiasts to follow us Just like the new PCs have fully transitioned to SSDs, today’s smartphones have also undergone a significant iteration, transitioning from eMMC flash to UFS flash. So, who influences the performance of UFS flash? Difference Between RAM and ROM Even now, many friends are unclear about the differences … Read more
Flash is a type of non-volatile memory that can retain data even when power is off. It is a form of electronically erasable programmable read-only memory (EEPROM) that allows for multiple erase and write cycles during operation. This technology is primarily used for general data storage and for transferring data between computers and other digital … Read more

Memory has become one of the most关注的半导体器件之一. This article will comprehensively explore the challenges faced by both old and new … Read more
Source: WeChat Official Account “Chip Theory” Introduction: Integrated circuits (chips) are manufactured layer by layer using photolithography technology. Therefore, the concept of “layers” exists in chip technology. So, how many concepts of “layers” are there in chip technology? Media reports say that Micron has launched a 176-layer 3D NAND flash memory chip; what does “layer” … Read more
Embedded Developers Essential Knowledge to Know Knowledge of ROM, FLASH, and Hard Drive Technology In embedded development, if the chip has internal Flash, the application program is usually stored in the internal FLASH of the chip, such as in Cortex-M series microcontrollers; if the chip does not have Flash, the application is usually stored in … Read more
As the storage field has developed, there are now many different types of storage products. Below, we will introduce several common storage types and their applications: 1. NAND NAND Flash memory is a type of Flash memory, which belongs to non-volatile memory. It uses a nonlinear macrocell architecture to provide a cost-effective solution for solid-state … Read more
