A pseudo-dual port memory performs both a first memory access operation
and a second memory access operation in a single period of an externally
supplied clock signal CLK. The signal CLK is used to latch a first
address for the first operation and a second address for the second
operation. Control circuitry generates first control signals that
initiate the first operation. The time duration of the first operation
depends upon a delay through a delay circuit. A precharge period follows
termination of the first operation. The time duration of the precharge
period depends upon a propagation delay through the control circuit. The
memory access of the second operation is initiated following termination
of the precharging. The time duration of the second memory access depends
on a delay through the delay circuit. The time when the second operation
is initiated is independent of the duty cycle of CLK.
