Abstract
In a selecting circuit for a memory operating mode, the circuit has a mode enable pulse generator which produces a short pulse for a mode enable pulse. A mode selecting clock generator which receives a mode enable pulse and selects a memory operating mode. The number of the mode selecting clock generator is determined by the number of memory operating mode to be used. A fuse, coupled with each of the mode selecting clock generators, is out when the corresponding mode selecting generator is selected and hence produces a mode selecting signal.
