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
