READ
after the /CAS Latency from the READ, followed by (BL-1) consecutive data when the Burst Length
is BL. The start address is specified by A0-9(x8)/A0-8(x16), and the address sequence of burst data
is defined by the Burst Type. A READ command may be applied to any active bank, so the row
precharge time (tRP) can be hidden behind continuous output data by interleaving the multiple banks.
When A10 is high at a READ command, the auto-precharge (READA) is performed. Any
command(READ,WRITE,PRE,ACT) to the same bank is inhibited till the internal precharge is
complete. The internal precharge starts at BL/2 after READA. The next ACT command can be
issued after (BL/2+tRP) from the previous READA.
After tRCD from the bank activation, a READ command can be issued. 1st Output data is available
