5 / 32 page GS8170DW36/72AC-350/333/300/250 Specifications cited are subject to change without notice. For latest documentation see http://www.gsitechnology.com. Rev: 1.04 4/2005 5/32 © 2003, GSI Technology Read Operations Pipelined Read Read operation is initiated when the following conditions are satisfied at the rising edge of clock: All three chip enables (E1, E2, and E3) are active, the write enable input signal (W) is deasserted high, and ADV is asserted low. The address presented to the address inputs is latched into the address register and presented to the memory core and control logic. The control logic determines that a read access is in progress and allows the requested data to propagate to the input of the output register. At the next rising edge of clock the read data is allowed to propagate through the output register and onto the output pins. Write Operations Write operation occurs when the following conditions are satisfied at the rising edge of clock: All three chip enables (E1, E2, and E3) are active, the write enable input signal (W) is asserted low, and ADV is asserted low.
