PRECHARGE Command

The PRECHARGE command is used to deactivate the open row in a particular bank or the open row in all banks. The

bank(s) will be available for a subsequent row activation a specified time (tRP) after the PRECHARGE command is issued,

except in the case of concurrent auto precharge, where a READ or WRITE command to a different bank is allowed as long

as it does not interrupt the data transfer in the current bank and does not violate any other timing parameters. Once a bank

has been precharged, it is in the idle state and must be activated prior to any READ or WRITE commands being issued to

that bank. A PRECHARGE command is allowed if there is no open row in that bank (idle bank) or if the previously open row

is already in the process of precharging. However, the precharge period will be determined by the last PRECHARGE

command issued to the bank.
