Title:
CURRENT CONTROL ELEMENT, MEMORY ELEMENT, MEMORY DEVICE, AND PRODUCTION METHOD FOR CURRENT CONTROL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/114666
Kind Code:
A1
Abstract:
Provided is a current control element that is able to prevent the occurrence of a write disturb even when electrical pulses with different polarities are applied, and that is able to apply a large current to a variable resistance element. The current control element is provided with a first electrode (32), a second electrode (31), and a current control layer (33). The current control layer (33) is composed of SiNx (0 < x ≤ 0.85), and contains hydrogen or fluorine. When the concentration of the hydrogen or fluorine is regarded as D (= D0 × 1022 atoms/cm3), the thickness of the current control layer (33) is regarded as d (nm), and the maximum voltage that can be applied between the first electrode (32) and the second electrode (31) is regarded as V0 (V), D, x, d and V0 satisfy (ln(10000(Cexp(αd)exp(βx))-1)/γ)2 ≤ V0, (ln(1000(Cexp(αd)exp(βx))-1)/γ)2 - (ln(10000(Cexp(αd)exp(βx))-1)/γ)2/2 ≥ 0 (where C = k1 × D0
k2, α, β, γ, k1 and k2 are constants).
