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 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.
