A method and apparatus for an apparatus and method for reduction of power consumption in OS that use flat segmentation memory model are described. In one embodiment, the method includes monitoring a segment register to detect a segment register update operation. Once the segment register update operation is detected, a code/data segment contained within the segment register is identified as one of a segmented code/data segment and a flat code/data segment. Once detected, the segment register is updated according to whether the segment is flat or segmented. Accordingly, when a segment register read is performed, one or more updated bits within the segment register are used to identify the code/data read from the segment register as either flat or segmented.
