Abstract
A flash memory controller includes a controllable delay circuit configured to receive a read strobe signal from a flash memory device and to delay the read strobe signal, a data latch, coupled to the controllable delay circuit, configured to receive the delayed read strobe signal, and to capture data from the flash memory device using the delayed read strobe signal, and a calibration circuit coupled to the controllable delay circuit, configured to instruct the controllable delay circuit to delay the read strobe signal at one of a plurality of delay settings, to receive the captured data from the data latch, to determine an accuracy of the captured data, and to determine an adjustment factor for the controllable delay circuit based on the accuracy of the data captured at the data latch.
