Note:
For this example, CL = 2, BL = 4 or greater, and DQM is LOW.
Concurrent Auto Precharge
An access command (READ or WRITE) to another bank while an access command with
auto precharge enabled is executing is not allowed by SDRAMs, unless the SDRAM
supports concurrent auto precharge. Micron SDRAMs support concurrent auto
precharge. Four cases where concurrent auto precharge occurs are defined below.
