Abstract
A memory architecture and a method of operating the same can provide a substantially constant data valid window (DVW) irrespective of a temperature for the memory device. Generally, a memory device can receive an access request, determine a temperature of the memory device, and switch a number of delay elements in an output buffer in response to the temperature of the memory device. In one embodiment, a memory device can have a multi-stage input-output (I/O) buffer and an automatic temperature compensated circuit that samples a temperature of the memory and then switches a number of delay elements in the I/O buffer into a data path between the memory and the output to provide a substantially constant DVW over changes in temperature.
