Abstract

See full text

Column address strobe write latency (CWL) calibration including a method for calibrating a memory system. The method includes entering a test mode at a memory device and measuring a CWL at the memory device. A difference between the measured CWL and a programmed CWL is calculated. The calculated difference is transmitted to a memory controller that uses the calculated difference for adjusting a timing delay to match the measured CWL.
