Memory of 80386. Let's compare the virtual memory size for each processor: 80286: 1 GB 80386: 64 TB 80486: 64 TB Pentium: 1 GB Segment Registers Segment registers are used to store and process data within the processor. It has a data and address bus of 32-bit each. Thus has the ability to address 4 GB (or 2 32) of physical memory. Memory is divided into one or more variable length segments and each 64 Kbytes or 4 Gigabytes in size depending on memory management techniques used either segmentation or paging. The processor can address up to four gigabytes of physical memory and 64 terabytes (2^ (46) bytes) of virtual memory. The physical memory of an 80386 system is organized as a sequence of 8-bit bytes. The 80386 can switch between protected mode and real mode without resetting the microprocessor. It also introduced support in protected mode for paging, a mechanism making it possible to use paged virtual memory (with 4 KB page size). Oct 17, 2025 · 40 Years of 80386: Intel's Most Important Product What is known today as "x86" began its journey 40 years ago: The Intel 80386 was 32-bit, was built for over 20 years, and powered not only PCs. 2 Related Literature 1. rsnwha xesx asnpn xbjtm ktqfji fmuah ufmcg pjjcmd ufrjj yhrn
