【摘要】：为提高三维存储器的成品率和减少冗余行列所需的TSVs的数量,提出每一层存储块都与相邻上下两层共享冗余的三维存储器冗余共享结构,并给出了一种新的堆叠方案,将故障较多与较少的芯片交替堆叠.实验结果表明,该结构在有效控制TSVs数量增长的前提下,提高了三维存储器的修复率.
[Abstract]:In order to improve the yield of 3D memory and reduce the number of TSVs needed for redundant columns, a redundant sharing structure of 3D memory is proposed in which each layer of storage blocks share redundancy with adjacent upper and lower layers, and a new stacking scheme is proposed. Alternately stack more faults with fewer chips. The experimental results show that the proposed structure can effectively control the growth of TSVs and improve the repair rate of 3D memory.
