Read and AutoPrecharge command
(RAS# = "H", CAS# = "L", WE# = "H", BAs = Bank, A10 = "H", A0-A8 = Column Address)
The Read and AutoPrecharge command automatically performs the precharge operation after the read
operation. Once this command is given, any subsequent command cannot occur within a time delay of
{
t
RP
(min.)
+ burst length
}
. At full-page burst, only the read operation is performed in this command and the auto precharge
function is ignored.
