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.
