a method and architecture that overcomes the problem of latency - caused performance degradation of electronic memory systems . the method involves a “ posted precharge ,” by which an external command for precharge is given as early as possible , such as immediately following a read command . the execution of the precharge is delayed by a precharge counter until all read / write commands are completed . by posting a precharge command on a bus at the first available opportunity , multiple pages can be open on the same bank of a memory device . as a result , access latencies are significantly reduced and efficiency of bus in electronic memory systems is significantly improved .
