After tRCD time from the bank activation, a WRITE command can be issued. 1st input data is sampled
at the WRITE command with data strobe input, followed by (BL-1) data being written into RAM.
The Burst Length is BL. The start address is specified by A12-A11,A9-A0(x4)/A11,A9-A0(x8), and the
address sequence of burst data is defined by the Burst Type. A WRITE command may be applied to any
active bank, so the row precharge time (tRP) can be hidden during the continuous input data by
interleaving the multiple banks. The write recovery time (tWR) is required from the last written data to
the next PRE command. When A10 is high in a WRITE command, the auto-precharge(WRITEA) is
performed. Any command(READ,WRITE,PRE,ACT) to the same bank is inhibited till the internal
precharge operation is completed. The next ACT command can be issued after tDAL
from the last input data cycle.
