Error Correction Requirements

Complex NAND Management• Complexity increasing with Tech• Higher ECC requirement• Bad block Management• Wear leveling

Performance is a challenge• Performance goes down with Tech• Needs creative Interleaving schemes

No Standard • NAND I/Fs varies with NAND vendors• Vendor-specific optimized commands• Timing varies with vendors
