4F² is a measure of area efficiency for DRAM memory chips, meaning each memory cell occupies only 4 times the minimum feature size in area, representing the theoretical limit of storage density, while mainstream DRAM today typically ranges between 6F² and 8F².

Unverified4-bit quantization (such as bitsandbytes NF4 or GPTQ) weights are usually stored in blocks, with each block carrying a scaling factor and zero point, and these metadata are often stored in FP16 or FP32; embedding layers, output layers, and normalization layers may remain at higher precision, so the actual weight file is typically 5%-15% larger than the theoretical P×b/8 value.75% similarVerified4-bit量化使模型存储空间缩减为FP16的约1/474% similarUnverified一张1024×1024的未压缩RGBA纹理占据4MB存储空间74% similarUnverifiedAccording to a Bilibili video, Changxin Memory successfully developed a 4F2 memory architecture, reducing the single-cell area by about 30% and raising the capacity ceiling of domestic HBM.72% similarVerifiedINT4 achieves 4× storage compression compared to FP16.72% similar
