A recently granted patent (Publication Number: US11881285B2) discloses a method and apparatus for providing access to a memory circuit. The method involves receiving a read enable input, initializing a wait state counter to count a predetermined number of clock cycles, monitoring the output of the wait state counter, receiving a memory ready signal from the memory circuit at a synchronizer input, monitoring the synchronizer output, and providing an ON-state data ready signal based on the elapsed wait state counter or the synchronizer output being in the ON-state.

Furthermore, the method includes provisions for providing stop signals between the synchronizer and the wait state counter based on the state of the synchronized ready signal output and the wait state counter. The apparatus comprises a wait state counter, a synchronizer, and a circuitry connected to the outputs of the wait state counter and the synchronizer, configured to provide the ON-state data ready signal. The wait state counter is designed to count clock cycles based on a worst-case estimate for memory access delay, ensuring efficient access to data output from the memory circuit.
