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 l
APR
is required before execution of the next command.
