Pin Descriptions SYMBOL TYPE DESCRIPTION Clock: CLK is driven by the system clock. All SDRAM input signals are sampled on the positive edge of CLK. CLK also increments the internal burst counter and controls the output registers. Input Clock Enable: CKE activates (HIGH) and deactivates (LOW) the CLK signal. Deactivating the clock provides PRECHARGE POWER-DOWN and SELF REFRESH operation (all banks idle), ACTIVE POWER-DOWN (row active in any bank), DEEP POWER DOWN (all banks idle), or CLOCK SUSPEND operation (burst/access in progress).
