Patent ID: 7295484

Claim:
An electronic system comprising: a first integrated circuit die including: an array of dynamic random access memory (DRAM) cells; a temperature sensor; refresh circuitry, the refresh circuitry for refreshing the DRAM cells of the array; refresh determination circuitry operably coupled to the temperature sensor, the refresh determination circuitry for generating requests to initiate a refresh cycle to refresh the array based upon a measured temperature of the temperature sensor; and an external output, the external output providing a refresh request indication externally from the first integrated circuit die, wherein the refresh request indication is indicative of a request to execute the refresh cycle of the array based upon the measured temperature of the temperature sensor; and a second integrated circuit die including: an input, the input coupled to receive the refresh request indication; and control circuitry, wherein the control circuitry of the second integrated circuit die utilizes the received refresh request indication to initiate the refresh cycle of the array.
