Detailed Example: Analyzing SSD Quality from NAND Flash Information

As the application of SSDs in the market increases, the importance of SSDs as a core component of computer data storage is self-evident. Due to the rising prices of NAND Flash in 2016 and the first half of 2017, the prices of SSDs have also surged. According to the China Flash Market quotation, from Q2 … Read more

Why Serial NAND Flash Does Not Support XiP?

Why Serial NAND Flash Does Not Support XiP?

Today, we will introduce the two main characteristics of serial NAND Flash that prevent it from supporting XiP under the i.MXRT FlexSPI. In the embedded world, when we mention XiP devices (memory that supports code execution in place), the first thing that comes to mind should be NOR Flash. For example, mid-range and low-end MCUs … Read more

How NAND Flash Is Manufactured

How NAND Flash Is Manufactured

NAND Flash is a type of non-volatile random access storage medium based on the design of floating gate transistors. It uses floating gates to store charges, which can be retained even without power supply. There has been a previous explanation of the basic principles of NAND Flash technology, which can be referenced in the article … Read more

Advantages of NOR Flash Memory Revisited

Advantages of NOR Flash Memory Revisited

Source: Content compiled from Semiconductor Industry Observer (ID: icbank) from eejournal, thank you. Before the semiconductor version emerged, ancient people tried various forms of computer memory. I think we can say that water-based capacitors provided a form of memory for the national income monetary simulation computer (MONIAC) manufactured in the UK in 1949. Notably, MONIAC … Read more
