WRITE
After tRCD from the bank activation, a WRITE command can be issued. 1st input data is set
at the same cycle as the WRITE. Following (BL -1) data are written into the RAM, when the Burst
Length is BL. The start address is specified by A0-A9,A11(x4), A0-9(X8), A0-8(X16) 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 behind continuous input data by
interleaving the multiple banks. From the last input data to the PRE command, the write recovery time
(tWR) is required. When A10 is high at a WRITE command, the autoprecharge (WRITEA) is
performed. Any command (READ, WRITE, PRE, ACT) to the same bank is inhibited till the internal
precharge is complete. The internal precharge begins at tWR after the last input data cycle. (Need to
keep tRAS min.) The next ACT command can be issued after tRP from the internal precharge timing.
