Abstract
A method for accessing a non-volatile memory comprises that an NVM controller receive a first access request from a processor and determines whether the first access request is used to access a page table. If the first access request is used to access the page table, the NVM controller obtains an AIT entry by reading a page table entry indicated by the first address information and caches the AIT entry to an AIT cache. The NVM controller monitors access of the processor to the page table, prefetches the to-be-accessed AIT entry.
