A semiconductor integrated circuit may include: a mode register and a clock delay control circuit. The mode register may store latency information corresponding to a plurality of frequencies. The clock delay control circuit may generate a delay clock signal using an external clock signal and the latency information. The delay clock signal may be used to control a timing margin of output data read during synchronous burst read operations of a non-volatile memory. A non-volatile memory device may include the semiconductor integrated circuit and a data output unit. The data output unit may use the delay clock signal to control the timing margin of the output data read during synchronous burst read operations. A memory system may include the semiconductor integrated circuit. A computing system may the semiconductor integrated circuit, as well as one or more of a memory controller, bus, modem, microprocessor, user interface, and battery.
