Abstract:
A computer, comprising:an electronic display;a plurality of memory banks configured to support page accesses and configured to present information stored therein to the electronic display;a memory controller coupled to said plurality of memory banks and adapted to control accesses to said plurality of memory banks, wherein said memory controller is further adapted to dynamically switch between a paging mode and an auto-precharge mode depending upon a hit:precharge ratio for accesses to said plurality of memory banks, wherein said memory controller comprises hit/precharge logic configured to determine if the current access is a page hit, a miss, or a miss requiring a precharge, wherein said hit:precharge ratio is the ratio of page hits to misses requiring a precharge;wherein when in said paging mode, after an access said memory controller leaves open the accessed page in said plurality of memory banks; andwherein when in said auto-precharge mode, said memory controller closes the accessed page in said plurality of memory banks after the access.
