The clock frequency must remain constant ( stable clock is defined as a signal cycling within timing constraints specified for the clock pin) during access or precharge states (READ, WRITE, including WR and Precharge commands). CKE may be used to reduce the data rate. 2. tHZ defines the time at which the output achieves the open circuit condition; it is not a reference to VOH or VOL. The last valid data element will meet tOH before going High-Z. 3. Paramater guaranteed by design 4. AC characteristics assume tT = 1ns 5. Auto precharge mode only) The precharge timing budget ( tRP) begins 7ns after the first clock delay, after the last Write is executed. 6. Precharge mode only. 7. CLK must be toggled a minimum of two times during this period.
