<P>PROBLEM TO BE SOLVED: To adjust timing to take in data. <P>SOLUTION: A receiver circuit includes: a mask generation section 37 of a memory interface circuit 12 for generating an inside mask signal CKM corresponding to a duration for receiving a data stream DQ on the basis of a strobe signal DQS (an inside strobe signal IRS) in synchronization with the data stream DQ; a DLL circuit 41 for generating an internal clock signal CKS obtained by delaying an internal clock signal CK2 according to a set value of a resister 41a; flip-flop circuits 33 and 34 for latching a reception data stream RDQ according to an inside strobing signal CST obtained by combining the internal mask signal CKM with the internal clock signal CKS by an AND circuit 38; and an adjustment circuit 50 for detecting the phase relationship between the internal mask signal CKM and the inside strobe signal CST on the basis of output signals from the DLL circuit 51 and 52, to update the set value of the register 41a to adjust a phase of the inside strobe signal CST. <P>COPYRIGHT: (C)2013,JPO&INPIT |
