Auto Precharge

Read with auto-precharge: In this operation, since precharge is automatically performed after completing a

read operation, a precharge command need not be executed after each read operation. The command

executed for the same bank after the execution of this command must be the bank active (ACTV) command.

In addition, an interval defined by IARP is required before execution of the next command.
