When FWS is included between 1 and 3, in case of sequential reads, the first access takes (FWS+1) cycles, the other ones only
1 cycle.
When FWS is included between 4 and 10, in case of sequential reads, the first access takes (FWS+1) cycles, each first access
of the 128-bit read (FWS-2) cycles, and the others only 1 cycle.
