Advanced Sorting Technology

SP Industrial implements Advanced Sorting Technology (AST) for NAND Flash testing and classification, specifically designed to meet the diverse temperature requirements of industrial customers.This technology precisely evaluates the durability and stability of NAND Flash memory; then accurately classifies it based on rigorous test results. This meticulous process ensures that the classified NAND Flash fully complies with the stringent demands of wide-temperature industrial 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 unusable blocks to ensure they are excluded from future data storage.

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 crucial technique for addressing the inherent limitations of NAND flash memory. It manages the wear rate across the entire NAND flash device, ensuring that each memory block is utilized as evenly as possible. Effective wear leveling is essential for maximizing the lifespan and reliability of the flash device.
