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
1. Introduction Previously, we sharedhttps://mp.weixin.qq.com/s/BeL6UbSg2HI9qKemZugOhw?token=1054074707&lang=zh_CN the article titled“Low-Cost Learning FPGA Based on“Mining Board”” which usesJTAG boundary scan for quick pin correspondence reverse engineering.. Not only forFPGAs, but we can also useJTAG for boundary scan testing inMCUs, provided that the corresponding chip supports this feature and the manufacturer providesBSDL files. Here, we will demonstrate using theLPC1857 … Read more
Introduction The STM32 provides flexible and diverse access implementations for external memory. This article will introduce how to utilize QSPI (QuadSPI) to implement external serial NOR Flash memory. First, the functional characteristics of the QSPI interface will be introduced, followed by hardware design and software development. Based on STM32CubeM, a reference implementation for accessing the … Read more

Welcome FPGA engineers to join the official WeChat technical group. This article mainly introduces the structure, external interfaces, and operations of NOR Flash. In NOR Flash, the ‘N’ stands for NOT, meaning that when there is a charge in the Floating Gate, it reads ‘0’, and when there is no charge, it reads ‘1’. This … Read more
To continuously improve various features in next-generation devices, wearable and hearable devices rely on memory. Memory is a key design factor for implementing advanced devices… Although wearable and hearable technologies may seem like extensions of the previous generation of handheld devices, the innovative features required to enhance their value, user experience, and functionality significantly increase … Read more
As the demand for faster, cheaper non-volatile memory alternatives continues to grow, especially in applications like automotive, resistive RAM is gaining renewed attention. Embedded flash memory has long left designers hoping for better write speeds and lower power consumption, but as the technology’s lead shrinks to 28 nanometers, another issue arises. Manufacturing flash memory at … Read more
