Abstract
A memory-access management method and system is provided for use with an DRAM (Dynamic Random-Access Memory) or the like, for the purpose of increasing the performance of memory access to the SDRAM by means of tracking the memory-access history of previous access operations. The memory-page management system has a managing device for managing the N memory pages. According to the embodiment, the managing device further comprises a page register unit. The page register unit is used for storing K storage units, each of which stores an address data of the memory page. The utilization-rate register unit is coupled to the page register circuit, and used for monitoring utilizations of the storage units. In practical design, the number K of the storage units can be designed to be less than the number N of the memory pages.
