Multiple electrode of low heat loss and small area of contact surface for phase change medium memory device

摘要: PROBLEM TO BE SOLVED: To reduce a current required for varying the condition of phase change medium. SOLUTION: An electrode structure low heat loss and small area contact surface memory device (10) is disclosed. The comprises multiple (12) that connected to substrate (11) contains dielectric mandrel (13) having tapered shape terminated at vertex (V). A conductive material (15) covers so as correspond therewith in shape, tip thereof. first layer (17) whole excepting an exposed part (E) adjacent (T). medium (19) with (E). shares few percentage total (12), foot print (AC) between respect (AM) (19). Thus transfer Joule (j h ) from reduced. COPYRIGHT: (C)2004,JPO
