A3V56S30FTP A3V56S40FTP 256M Single Data Rate Synchronous DRAM A3V64S40GTP-60 Pin Function 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.
