Abstract
This disclosure describes a clock circuit for a memory controller. The described circuit uses a processor clock signal to generate an input clock signal for use during write operations to the memory, or to generate a feedback clock signal for use during read operations from the memory. The circuit is particularly applicable to mobile wireless devices that include memories that do not generate a strobe. The clock circuit may comprise a driver in series with a resistor element that generates an input clock signal for input to a memory, and a resistor-capacitor (RC) filter in series with a receiver that generates a feedback clock signal for output from the memory, wherein an input to the RC filter is tapped between the driver and the resistor element.
