PURPOSE: An output enable signal generation circuit of a semiconductor memory is provided to secure the activation and inactivation of a section signal by dividing circuit configuration of determining the activation and inactivation of the section signal. CONSTITUTION: In an output enable signal generation circuit of a semiconductor memory, a latency signal generating unit(200) generates a latency signal. The latency signal defines the activation timing of a data output enable signal. A data output enable signal generator(400) adjusts the activation timing and inactivation timing of the data output enable signal. A latency signal generating unit comprises a plurality of latency signal generating units(210~260) The latency signal generating unit comprises a selecting unit(270) which selects one reserved latency signal.
