Sorting

To meet the needs of industrial customers operating under various temperature conditions, SP employs Advanced Sorting Technology (AST) for NAND Flash testing and classification. This technology accurately evaluates the durability and stability of NAND Flash and classifies them based on test results to meet the strict requirements of wide-temperature applications.

Garbage Collection

Solid-state drives (SSDs) utilize NAND flash memory to store data, employing a process managed by the controller to ensure efficient storage and retrieval. Unlike traditional storage methods, SSDs cannot directly overwrite old data with new data. Instead, the existing data in the relevant block must first be erased before new data can be written. This process is facilitated through a mechanism known as Garbage Collection.

Bad Block Management

Bad Block Management is a mechanism used by the controller in flash memory to detect and handle bad blocks. It identifies and marks defective blocks, ensuring they are not used for data storage again. To maintain data reliability, the controller replaces bad blocks with reserved spare blocks, which helps prevent data corruption and improves the overall reliability and lifespan of the memory.

pSLC

SP Industrial bridges the gap between SLC and MLC/3D TLC solutions with pseudo-SLC (pSLC) Flash, a more advanced variant of MLC/3D TLC. pSLC offers faster speeds, higher program/erase cycle endurance, and better reliability than standard MLC/3D TLC, while being more cost-effective than SLC. It operates similarly to SLC but has fewer program/erase cycles, making it an efficient choice for applications demanding high endurance.

Wear Leveling

Wear leveling is a key solution for managing the limited program/erase (P/E) cycles of NAND flash memory. By evenly distributing wear across memory blocks, wear leveling extends the lifespan and reliability of flash devices. SP Industrial SD and microSD cards incorporate three wear leveling techniques: dynamic, static, and global.
