About Pebibits
A pebibit (Pibit) = 2⁵⁰ bits (IEC 80000-13). Intel LA57 5-level paging extends virtual addressing to 57 bits = 128 PiB = 1 Pibit of byte-addressable virtual memory space per process. The Frontier supercomputer (ORNL, 2022) has ≈700 PiB = 5,600 Pibit of total Lustre storage. AMD EPYC Milan-X supports up to 52-bit physical addresses (4 PiB). 1 Pibit = 2⁵⁰ bits = 128 TiB.
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.
