The BURST TERMINATE command is used to truncate READ bursts with auto pre-
charge disabled. The most recently registered READ command prior to the BURST
TERMINATE command will be truncated, as described in READ Operation (page 57).
The open page from which the READ was terminated remains open.
AUTO REFRESH is used during normal operation of the device and is analogous to CAS#-
BEFORE-RAS# (CBR) REFRESH in FPM/EDO DRAM. The AUTO REFRESH command is
nonpersistent and must be issued each time a refresh is required.
Addressing is generated by the internal refresh controller. This makes the address bits a
“Don’t Care” during an AUTO REFRESH command.
For improved efficiency in scheduling and switching between tasks, some flexibility in
the absolute refresh interval is provided. The auto refresh period begins when the AU-
TO REFRESH command is registered and ends
