Abstract
A temperature control circuit, comprising: a plurality of temperature sensors each configured to measure a temperature of a corresponding memory chip chosen from a plurality of memory chips, and to generate a sensor output signal that is set to a first voltage if the measured temperature of the corresponding memory chip meets a temperature requirement, and is set to a floating voltage if the measured temperature of the corresponding memory chip does not meet the temperature requirement, the sensor output signal being connected to an intermediate node; a current source connected to the intermediate node; and a control circuit configured to provide chip control signals to the plurality of memory chips.
