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.
About Mebibits
A mebibit (Mibit) = 2²⁰ = 1,048,576 bits (IEC 80000-13). Used in JEDEC DRAM die specs (DDR5 16-Gibit die = 2 GiB) and FPGA block RAM. NVIDIA Ampere SM: 128 KiB = 1 Mibit of L1 cache/shared memory per SM. STM32H7 Cortex-M7: 1 Mibit tightly coupled data RAM. The 6502 (Apple II, C64) addressed 512 Kibit = 64 KiB of RAM. 1 Mibit = 1,048,576 bits = 128 KiB.
