A memory access mode detection circuit and method for detecting and
initiating memory access modes for a memory device The memory access mode
detection circuit receives the memory address signals, the control
signals, and the clock signal and generates a first mode detection signal
in response to receipt of the memory address signals or a first
combination of control signals. An first mode initiation signal is
generated a time delay subsequent to the detection signal to initiate the
first mode memory access operation. In response to receipt of a second
combination of control signals and an active clock signal, the memory
access mode detection circuit further generates a second mode detection
signal to initiate a second mode memory access operation and to suppress
generation of the first mode detection signal, thereby canceling the
first mode memory access operation.
