摘要:
A method and apparatus implement memory accesses to a memory using an open page mode with data prefetching. A central processor unit issues memory commands. A memory controller receiving the memory commands, identifies a data prefetching command. The memory controller checks whether a next sequential line for the identified prefetch command is within the page currently being accessed, and responsive to identifying the next sequential line being within the current page, the current command is processed and the current page left open.
