Memories have been considered as one of the major drivers of CMOS technology, due to their high density, high capacity, critical timing, sensitivity, etc. Memory diagnosis is therefore important for technology and product development. Memory failure pattern identification is traditionally an essential task for diagnosis. As memory density and capacity continue to grow, the amount of test data also...
Three-dimensional stacked memory stacking logic and memory dies are one of the most promising 3-D integration applications. This paper proposes two memory redundancy schemes to improve the yield of channelbased 3-D stacked DRAM by sharing spare memory across dies and satisfying channel constraints at the same time. The proposed schemes achieve much higher yield with very small area overhead than other...
Due to more aggressive design rules adopted by memories than logic circuits, memories have been considered as the major technology driver of advanced logic circuits, so far as CMOS process technology is concerned. Memory failure pattern identification therefore is important, and is traditionally considered a key task that can help improve the efficiency of memory diagnosis and failure analysis. Critical...
The three-dimensional integrated circuit (3D IC) is considered a promising approach that can obtain high data band-width and low power consumption for future electronic systems that require high integration level. One of the popular drivers for 3D IC is the integration of a memory stack and a logic die. Because the yield of a 3D IC is the product of respective yields of the mounted dies, the yields...
Redundancy repair is a commonly-used technique for memory yield improvement. In order to ensure high repair efficiency and final product yield, it is necessary to explore and develop the memory redundancy architecture carefully. However, due to the different failure distributions of memory arrays and various design constraints of memory architectures, it is difficult to explore the efficiency of the...
