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
