The bistable resistance random access memory comprises two memory layer stacks per memory cell, the bistable resistance random access memory operates in four logic states, a logic “00” state, a logic “01” state, a logic “10” state and a logic “11” state. The relationship between the four different logic states can be represented mathematically by the two variables n and f and a resistance R. The logic “0” state is represented by a mathematical expression (1+f)R. The logic “1” state is represented by a mathematical expression (n+f)R. The logic “2” state is represented by a mathematical expression (1+nf)R. The logic “3” state is represented by a mathematical expression n(1+f)R.

    摘要: A bistable resistance random access memory is described for enhancing the data retention in a resistance random access memory member. A dielectric member, e.g. the bottom dielectric member, underlies the resistance random access memory member which improves the SET/RESET window in the retention of information. The deposition of the bottom dielectric member is carried out by a plasma-enhanced chemical vapor deposition or by high-density-plasma chemical vapor deposition. One suitable material for constructing the bottom dielectric member is a silicon oxide. The bistable resistance random access memory includes a bottom dielectric member disposed between a resistance random access member and a bottom electrode or bottom contact plug. Additional layers including a bit line, a top contact plug, and a top electrode disposed over the top surface of the resistance random access memory member. Sides of the top electrode and the resistance random access memory member are substantially aligned with each other.

    摘要: A semiconductor structure with improved capacitance of bit lines includes a substrate, a stacked memory structure, a plurality of bit lines, a first stair contact structure, a first group of transistor structures and a first conductive line. The first stair contact structure is formed on the substrate and includes conductive planes and insulating planes stacked alternately. The conductive planes are separated from each other by the insulating planes for connecting the bit lines to the stacked memory structure by stairs. The first group of transistor structures is formed in a first bulk area where the bit lines pass through and then connect to the conductive planes. The first group of transistor structures has a first gate around the first bulk area. The first conductive line is connected to the first gate to control the voltage applied to the first gate.

    摘要: An air tunnel floating gate memory cell includes an air tunnel defined over a substrate. A first polysilicon layer (floating gate) is defined over the air tunnel. An oxide layer is disposed over the first polysilicon layer such that the oxide layer caps the first polysilicon layer and defines the sidewalls of the air tunnel. A second polysilicon layer, functioning as a word line, is defined over the oxide layer. A method for making an air tunnel floating gate memory cell is also disclosed. A sacrificial layer is formed over a substrate. A first polysilicon layer is formed over the sacrificial layer. An oxide layer is deposited over the first polysilicon layer such that the oxide layer caps the first polysilicon layer and defines the sidewalls of the sacrificial layer. A hot phosphoric acid (H3PO4) dip is used to etch away the sacrificial layer to form an air tunnel.
