A one-selector one resistor (1S1R) array formed of a selector and resistive random access memory (RRAM) is an important way to achieve high-density storage and neuromorphic computing. However, the low durability and poor consistency of the selector limit its practical application. The fabrication of a selector based on egg albumen (EA) is reported in this paper. The device exhibits excellent bidirectional threshold switching characteristics, including a low leakage current (10 A), a high ON/OFF current ratio (10 ), and good endurance (>700 days). It is used as a selector to form a 1S1R unit in combination with an EA-based RRAM to effectively solve the leakage current in a crossbar array. A feasible solution is provided for the realization of a protein-based 1S1R array to achieve high-density storage. The 1S1R unit shows characteristics similar to those of synapses in the human brain under impulse excitation and has great potential in simulating the human brain for neuromorphic calculations.).
由选择器和电阻式随机存取存储器 (RRAM) 组成的单选择器单电阻器 (1S1R) 阵列是实现高密度存储和神经形态计算的重要途径。然而，选择器的低耐久性和差的一致性限制了其实际应用。本文报道了一种基于蛋清 (EA) 的选择器的制造。该器件表现出优异的双向阈值开关特性，包括低泄漏电流 (10 A)、高导通/截止电流比 (10 ) 和良好的耐久性 (>700 天)。它被用作选择器，与基于 EA 的 RRAM 结合形成 1S1R 单元，可有效解决交叉阵列中的泄漏电流问题。为实现基于蛋白质的 1S1R 阵列以实现高密度存储提供了可行的解决方案。1S1R 单元在脉冲激励下表现出类似于人脑突触的特性，在用于神经形态计算的模拟人脑方面具有巨大的潜力。
