... The IC41C16257/IC41LV16257 CAS function is determined by the first CAS (LCAS or UCAS) transitioning LOW and the last transitioning back HIGH. The two CAS controls give the IC41C16257 both BYTE READ and BYTE WRITE cycle capabilities. Memory Cycle A memory cycle is initiated by bringing RAS LOW and it is terminated by returning both RAS and CAS HIGH ...
