What is NOR Flash? NOR Flash is an electronically erasable and reprogrammable non-volatile computer storage medium that uses “NOR” logic gate circuits. Origin of NOR Flash Technology In 1980, Toshiba’s Fujio Masuoka applied for a patent for simultaneously erasable EEPROM, which was later named Flash. In 1984, Masuoka presented the complete concept of NOR Flash … Read more
The storage chip sector has been the most eye-catching on 10/24, with the hype around storage chips having been ongoing for several months. Let’s take a closer look at this sector;First, let’s examine the specific types of storage chips【Excerpt from Yuanbao】: Storage chips are one of the core branches of the semiconductor industry. They can … Read more
Use the preprocessor directive #define to declare a constant that indicates how many seconds are in a year (ignoring leap years): #define SECONDS_PER_YEAR (60 * 60 * 24 * 365)UL Write a standard macro MIN that takes two parameters and returns the smaller one: #define MIN(A,B) ((A) <= (B) ? (A):(B)) What is the purpose … Read more
In this article, we will explore the qualifiers in C programming (const and volatile). This is a very important topic in C and embedded systems. In interviews, this is often the first question about the C language. What is the volatile keyword? Why use volatile? What is the difference between const and volatile? What are … Read more
Hello everyone, I am Xiao Feng Ge. When learning C language, there is a strange keyword volatile, what is its use? volatile and the Compiler First, let’s look at this piece of code: int busy = 1; void wait() { while(busy) { ; }} Compile it, and note that O2 optimization is used here:Let’s take … Read more

EEPROM is an Electrically Erasable Programmable Read-Only Memory with non-volatile characteristics, widely used for storing device parameters. Its core is based on a floating-gate transistor structure, allowing for byte-level erasure and writing (with a lifespan of 100,000 to 1,000,000 cycles). Compared to EPROM, it does not require ultraviolet light for erasure, making it more convenient … Read more
In the C language, <span>volatile</span> is a type specifier that informs the compiler that the variable it modifies may be changed by factors outside the program (such as hardware, interrupt service routines, etc.). Therefore, the compiler should not optimize this variable, and it must read its value from memory each time it is used, rather … Read more

Basic Principles and Structure of NAND Flash What is NAND Flash?NAND Flash (flash memory) is a type of non-volatile memory technology primarily used for data storage. Unlike traditional DRAM or SRAM, NAND Flash retains data even … Read more
In embedded system development, the ‘volatile’ keyword is a very important modifier that tells the compiler that the value of a variable may change outside the control of the program. Correctly using the volatile keyword can prevent errors caused by compiler optimizations, ensuring the correctness and reliability of the code. This article will detail the … Read more
