Read with Auto Precharge
If A10 is high when read command is issued, DRAM perform read with auto precharge. When read with auto pre-
charge command is issued, internal Precharge start automatically. If tRAS minimum is satisfied, internal precharge
start at AL+BL/2 cycles later. If tRAS minimum is not satisfied, internal precharge starting point is delayed until tRAS
minimum is satisfied. A new active command can be issued to the same bank if the following two conditions are satis-
fied simultaneously.
1. The RAS precharge time (tRP) has been satisfied from the clock at which the auto precharge begins.
2. The RAS cycle time (tRC) from the previous bank activation has been satisfied.
