Calibration device for relative phase of two reception signals of memory module, includes correction device for influencing relative phase between signals sent to memory module

摘要

A calibration device for adjusting the relative phase between two signals (CLK, DTS) which are generated in a controller in synchronism to one another and then sent via separate lines to the storage module. A measurement device (40) measures the relative phase between the two received signals and a feedback loop containing a phase controlled correction device (60) and the measurement device (40) is designed for generating adjustment or setting information (STL). The correction circuit (60) is arranged in the controller (110) and is designed for influencing the relative phase between the two signals to be sent to the storage module (120), and the feedback loop contains a feedback signal connection (RLDL) leading from the storage module (120) to the controller (110). An independent claim is included for an arrangement of several calibration devices.
