Test Mode field (A8~A7)
Write Burst Length (A9)
This bit is used to select the burst write length.

These two bits are used to enter the test mode and must be programmed to “00”in normal operation.
No-Operation command
(RAS# =”H”, CAS# =”H”, WE# =”H”)
is Low).This prevents unwanted commands from being registered during idle or wait states.
Burst Stop command
(RAS# =”H”, CAS# =”H”, WE# =”L”)
The Burst Stop command is used to terminate either fixed-length or full-page bursts.This
command is only effective in a read/write burst without the auto precharge function.The terminated
read burst ends after a delay equal to the CAS# latency (refer to Figure "Termination of a Burst Read
Operation"). The termination of a write burst is shown in the Figure "Termination of a Burst Write Operation".
