Abstract
A method and apparatus for selective automatic precharge of dynamic random access memory banks is disclosed. By automatically precharging memory banks under certain conditions overall memory throughput can be improved because precharging is performed on a more selective basis. In one embodiment, the present invention provides support for multiple open banks of memory within a single memory sub-system. When multiple banks of memory are open simultaneously, a bank of memory that is less likely to be accessed in the future can be precharged when a new bank of memory is to be opened to service a memory request.
