Memory management for a hierarchical memory system

摘要

Disclosed are systems and methods for managing memory. A memory management system may include a table having multiple virtual memory addresses. Each virtual memory address may correspond to a physical memory address and data that identifies a type of memory device corresponding to the physical memory address. The physical memory device can be used to access the memory device when a table hit occurs.

主权项

1. A memory management system comprising:
a first memory translation table configured to associate a first virtual memory address to a first physical memory address, to first data that indicates how frequently the first physical memory address is accessed, and to second data that identifies a first memory type of a first memory device comprising the first physical memory address; a second memory translation table configured to associate a second virtual memory address to a second physical memory address, to third data that indicates how frequently the second physical memory address is accessed, and to fourth data that identifies a second memory type of a second memory device comprising the second physical memory address; and a control unit configured to control operation of the first memory device and the second memory device based at least in part on the first memory translation table and the second memory translation table.
