Single write
A single write operation is enabled by setting OPCODE (A9, A8) to (1, 0). In a single write operation, data is
only written to the column address and the bank select address (BA) specified by the write command set cycle
without regard to the burst length setting. (The latency of data input is 0 clock).

Auto Precharge
Read with auto precharge:
In this operation, since precharge is automatically performed after completing a
read operation, a precharge command need not be executed after each read operation. The command executed
for the same bank after the execution of this command must be the bank active (ACTV) command. In
addition, an interval defined by I
APR
is required before execution of the next command.
