* Note : 1. BRSW mode is enabled by setting A9 “High” at MRS (Mode Register Set).
At the BRSW Mode, the burst length at write is fixed to “1” regardless of programed burst length.
2. When BRSW write command with auto precharge is executed, keep it in mind that tRAS should not be violated.
Auto precharge is executed at the burst-end cycle, so in the case of BRSW write command,
The next cycle starts the precharge.
