In embedded systems, EEPROM (Electrically Erasable Programmable Read-Only Memory) is often used to store data that needs to be changed frequently and should not be lost due to power interruptions. However, since STM32 does not have built-in EEPROM, how can we solve this problem and meet storage requirements? 1. Use External EEPROM Chips When STM32 … 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
In 2016, the configuration of Android phones was upgraded to a new level, featuring the Snapdragon 820, 4GB of RAM, and storage capacity soaring to 128GB. A small detail here is that it adopted UFS 2.0 flash memory instead of the previously popular eMMC 5.1. So, what exactly is UFS 2.0 flash memory? Why are … 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
