Semiconductor memory e.g. dynamic RAM, device, has device sensing current temperature, where memory device can be operated in energy saving mode for pre-defined time, which begins during activation of control signal

摘要

The device has a temperature sensing device for sensing current temperature, where sensing is induced by a control signal (ZQC). The semiconductor memory device can be operated in an energy saving mode for a pre-specified time, which begins during an activation of the control signal. The energy saving mode has no energy consumption. The energy saving mode is an open-circuit operation condition or a switch off mode. The energy saving mode is a non access mode, in which an access to a memory core is not executed. An independent claim is also included for a method for controlling a semiconductor memory device.
