摘要:
Memory devices may have a memory array and a delay locked loop (DLL) circuit that adjusts signals associated with operations to access of the memory array. The memory device may also include a controller that delays an access command to access the memory array by transmitting the access command through delay circuitry of the DLL circuit. This may cause the access command to be delayed by a first duration of time when output from the delay circuitry. Delay of the access command may align a data signal and the access command such that the access command and a system clock may cause latching of suitable data of the data signal.
