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.
About Zebibits
A zebibit (Zibit) = 2⁷⁰ bits ≈ 1.18 × 10²¹ bits (IEC 80000-13). Total world manufactured digital storage in 2023 (≈ 10,000 EB ≈ 80,000 Ebit) is ≈ 67,000× smaller than 1 Zibit. A 70-bit byte address space would address 2⁷⁰ bytes = 128 ZiB of memory - far beyond any foreseeable architecture. At projected HDD areal density (10¹² bits/cm²), 1 Zibit would require ≈ 10⁹ cm² ≈ the area of Iceland. 1 Zibit = 2⁷⁰ bits = 128 EiB.
