2. 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 exe-
cuted for the same bank after the execution of this command must be the bank active (ACTV) command. In
addition, an interval defined by l
APR
is required before execution of the next command.
