Wear Leveling in SSD/UFS: An Overview

Wear Leveling in SSD/UFS: An Overview

Wear Leveling, abbreviated as WL, is a technique used to ensure that each flash memory block in SSD/UFS maintains a similar number of erase and write cycles.Each flash memory block has a limited lifespan, with a maximum number of erase cycles. When the erase count of a block exceeds a certain threshold, that block becomes … Read more

STM32 Flash: Sector, Page, Block

THANK YOUClick the blue text to follow me In STM32 Flash memory, sectors (Sector), pages (Page), and blocks (Block) are hierarchical concepts based on storage management needs, with the core goal of balancing “erase efficiency” and “storage flexibility”—the physical characteristics of Flash dictate thatit can only be erased in fixed minimum units (data becomes all … Read more

LevelX: An Embedded Flash Memory ‘Balancing Master’ to Solve Issues of Uneven Flash Lifespan, Bad Blocks, and Data Loss During Power Outages

Hello, friends! If you’ve ever worked with NAND/NOR Flash, you surely understand the pain: after tens of thousands of erase/write cycles, some blocks start to ‘fail’, leading to data loss and performance degradation… It’s frustrating! Today, let’s talk about a powerful tool—LevelX, which can perform a perfect ‘check-up’ and ‘exercise’ for your embedded flash memory, … Read more

The AI Robot as a Legacy

The boy was obliterated in a silent accident, like an equation on the sand erased by the tide. The world he inhabited—a house filled with warm yellow lights and scattered LEGO bricks—suddenly collapsed into a geometric point, heavy beyond measure. What remained, besides the void, was his dedicated AI agent: a smooth, minimalist white cube … Read more

The Most Detailed SPI Protocol Analysis on the Internet

Click the blue text Follow us 1. Principle The SPI (Serial Peripheral Interface) protocol is a high-speed, efficient, full-duplex communication bus that allows the CPU to perform synchronous serial data transmission with low-speed peripheral devices. It mainly uses a synchronous clock signal to simultaneously send and receive serial data, thus achieving full-duplex communication. It is … Read more
