Abstract
Technology is disclosed herein for correcting skew between data signals and a clock signal. In one aspect, a memory system has a delay circuit having delay blocks, with each delay block having one or more inverters. The delay circuit is configured to pass a data signal through either an odd number of the inverters or an even number of the inverters to produce a delayed data signal. The memory system has a skew correction circuit configured to control the number of inverters in the delay circuit through which the data signal is passed in order to correct skew between the data signal and the clock signal. The memory system has a polarity correction circuit configured to invert the data signal in the event that the delay circuit passed the data signal through the odd number of the inverters.
