Abstract
An energy-saving device for a memory circuit. The energy-saving device is capable of immediately terminating a local sense amplifier enable signal to a sense amplifier. The energy-saving device employs a plurality of Schmitt triggering circuits with each Schmitt triggering circuit capable of receiving an operational signal and an inverse operational signal and capable of issuing a Schmitt triggering signal to a data-transmission tester. The data-transmission tester will issue a response signal when change in the Schmitt triggering signal is detected. A data-transition-detected pulse is sent from a data-transmission-testing pulse generation circuit to a power shut down signaling circuit to terminate the local sense amplifier enable signal when the data-transmission-testing pulse-generation circuit receives a response signal.
