Abstract:
1. A phase change memory, comprising: a first heater element having a sublithographic thickness in a first direction and first and second ends; a first pair of dielectric spacers positioned on opposite sides of the first heater element, the first pair of dielectric spacers being of a first dielectric material and each having a sublithographic thickness in the first direction; a first storage element of phase change material having first and second ends and a sublithographic thickness in a second direction that is transverse to the first direction, the first end of the storage element contacting the second end of the heater element along the first and second directions; and a second pair of dielectric spacers positioned on opposite sides of the first storage element, each dielectric spacer of the second pair having a sublithographic thickness in the second direction.
