About Bits
The bit (b) is the fundamental unit of digital information - a single binary digit: 0 or 1. Coined by John Tukey in 1948; formalised by Claude Shannon. Physically realised as transistor states (SRAM/DRAM), magnetic domains (HDD), charge levels in NAND flash (MLC=2, TLC=3, QLC=4 bits per cell). Shannon entropy: a coin flip = 1 bit; a card drawn from a 52-card deck ≈ 5.7 bits. 1 bit = 1/4 nibble = 1/8 byte.
About Gibibits
A gibibit (Gibit) = 2³⁰ = 1,073,741,824 bits (IEC 80000-13). JEDEC primary capacity unit for DRAM dies: LPDDR5 dies rated at 4/8/16/32 Gibit. HBM2e/HBM3: each die = 16 Gibit = 2 GiB (JEDEC JESD235E); HBM3 12-die stack = 192 Gibit = 24 GiB. NVIDIA H100 SXM 80 GiB = 640 Gibit across 5 HBM3 stacks. 1 Gibit = 2³⁰ bits = 128 MiB.
