Introduction In embedded development, have you ever encountered a scenario where the value of a global variable suddenly changes? The interrupt service routine has modified it, yet the main program continues to read the old value. Even more frustrating, these issues are often difficult to reproduce, making debugging feel like “catching ghosts.” The root cause … Read more
NAND Flash and NOR Flash are two common types of flash memory.NOR Flash was first developed by Intel in 1988, changing the landscape that was previously dominated by EPROM and EEPROM.NAND Flash was released by Toshiba in 1989, emphasizing lower cost per bit, higher performance, and the ability to be easily upgraded through interfaces like … Read more
Source: Semiconductors and Physics Original Author: Yi Zheke Floating gate transistors are mainly used in non-volatile memory, such as the basic unit in NAND flash. This article introduces the structure and principle of floating gate transistors. The above image shows the basic composition of a floating gate transistor, which adds a floating gate layer between … Read more
