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 Megabytes
A megabyte (MB) = 1,000,000 bytes (SI). Used by all storage manufacturers and by macOS (since 10.6), iOS, and Android. Typical file sizes: JPEG photo (50 MP) = 8-20 MB; 3-min MP3 at 128 kbit/s ≈ 2.9 MB; Android productivity APK 10-150 MB; full-frame RAW photo (Sony A7R V, 61 MP) 60-120 MB. H.264/H.265 achieves 30-100× compression vs. raw video. 1 MB = 1,000,000 bytes = 1,000 KB.
