Application Number: JP,2022-003792
Category (FI): G06F12/1009,100,G06F15/167,610@Z
Stage: PROBLEM TO BE SOLVED: To provide a system, a method, a program, and a storage medium for memory power supply management for executing management in a coherent lower power state.SOLUTION: A memory subsystem provided with a memory managed by using coherent access manages a page table entry so as to enable the memory to be in a lower power state. Memory control can change the page table entry of the memory before triggering the memory so as to be entered to the low power state. The change to the page table entry causes a page fault to the next access to the memory. The page fault triggers processing using a fault routine to the access to the memory, and avoids synchronization delay to the memory which occurs in the case of being normal access.SELECTED DRAWING: Figure 3 (Grant)
