PLC NAND Flash – Technical Principles, Challenges and Future Outlook
On the path of technological evolution, from SLC storing 1 bit per cell, to MLC with 2 bits, TLC with 3 bits, and QLC with 4 bits, each step represents a new balance between cost and reliability. Today, PLC technology, storing 5 bits of data per cell, is seen as a key development direction for next-generation high-density storage.
