An electronic device, such as a bubble memory (21), which has a narrow temperature band of operation, is maintained within the narrow temperature band by a Peltier circuit (30). The Peltier circuit (30) includes a Peltier junction (31) which is placed in a heat conducting relationship with the bubble memory (21). The Peltier circuit (30) has the advantage of being able to alternately heat or chill the bubble memory device (21) in order to maintain the bubble memory device (21) within its recommended temperature range.
