Flat vs. segmented memory – it's recursive

Rambles around computer science Diverting trains of thought, wasting precious time 25 08 2026--> Tue, 25 Aug 2026 Flat vs segmented memory -- it's recursive My recent forays in x86 segmentation (1 2) made me notice a trend in the evolution of x86: the decline of fine-grained memory protection, both across the move to 64-bit and indeed before that in the fast system calling features. These both partially hobbled the sophisticated segmentation system, which had been a hallmark of the architecture
