Burst Read
The read cycle is started by executing the read command.
The address provided during read command execution is
used as the starting address. First, the data corresponding
to this address is output in synchronization with the clock
signal after the CAS latency period. Next, data corresponding
to an address generated automatically by the device is
output in synchronization with the clock signal.
The output buffers go to the LOW impedance state CAS
latency minus one cycle after the read command, and go
to the HIGH impedance state automatically after the last
data is output. However, the case where the burst length
Burst Write
The write cycle is started by executing the command. The
address provided during write command execution is used
as the starting address, and at the same time, data for this
address is input in synchronization with the clock signal.
Next, data is input in other in synchronization with the clock
signal. During this operation, data is written to address
generated automatically by the device. This cycle
terminates automatically after a number of clock cycles
determined by the stipulated burst length. However, the
case where the burst length is a full page is an exception.
In this case the write cycle must be terminated by executing
