[ /CAS LATENCY]
/CAS latency,CL,is used to synchronize the first output data with the CLK frequency,i.e.,the
speed of CLK determines which CL should be used.First output data is available after CL
cycles from READ command.

[ BURST LENGTH ]
The burst length,BL,determines the number of consecutive wrutes or reads that will be
automatically performed after the initial write or read command.For BL=1,2,4,8,full page the
output data is tristated(Hi-Z) after the last read.For BL=FP (Full Page),the TBST (Burst
Terminate) command should be issued to stop the output of data.
