Title: Method reducing latency of writing data in memory
Inventor: CHEN JIA-SHIN
IPC: G06F12/08
Filed: 1998-11-20
Granted: 2000-05-01
Abstract: The control method of efficaciously reducing the delay time of writing data in memory is presented. When the memory control circuit receives a write-in request from CPU, it will send a virtual request to memory circuit after finishing current process. If the address is not in the opened page, the memory circuit will proceed to pre-charge itself and activate to open the memory page needed, when the CPU sends out the write-in data, it then sends the actual write-in request to memory circuits. So the memory circuit can write the data in the opened page right away and thus effectively reduce the delay time of writing data in memory.
