Abstract
A dynamic random access memory (DRAM) with multiple thermal sensors disposed therein and a control method for the DRAM. A DRAM in accordance with an exemplary embodiment of the invention provides multi-zone temperature detection. The DRAM comprises a plurality of banks, a plurality of thermal sensors and a control unit. The thermal sensors are disposed between the banks. The control unit controls the thermal sensors to obtain sensed temperatures, and sets a self-refresh cycle for all of the banks based on the highest one of the sensed temperatures.
