Abstract
A device comprising a temperature-dependent self refresh circuit for a memory device is provided where the self refresh circuit includes: a temperature sensor circuit for providing an output that reflects an operation temperature; means for switching the temperature sensor circuit to a low power state during a self refresh operation; an encoder for encoding temperature data from said output; and a programmable oscillator responsive to the encoded data to provide a temperature-dependent refresh signal for the self refresh operation.
