Dear IEEE JETCAS Readers, 

The IEEE Journal on Emerging and Selected Topics in Circuits and Systems (JETCAS) proudly published its June 2026 issue. This special issue aims at promoting In-Memory-Computing (IMC) and its applications as a promising solution. Both today's computer architectures and device technologies (used to manufacture them) are facing major challenges, making them incapable of delivering the performance required by complex applications, such as Artificial Intelligence (AI). The complexity stems from the extremely high number of operations to be computed and the amount of data involved. The direct consequence is that the computational workload involved in such applications is limited by the well-known walls of actual computing systems: (1) The Memory wall due to the increasing gap between processor and memory speeds, and the limited memory bandwidth making the memory access the performance killer and power drain for memory access dominated applications; (2) The Power wall, concerning the practical power limit for cooling, which means no further increase in CPU clock speed.  Nanoscale CMOS technology, which has been the enabler of the computing revolution, also faces three walls: (1) The Reliability wall as technology scaling leads to reduced device lifetime and higher failure rate, (2) The Leakage wall as the static power is becoming dominant at smaller technologies (due to the volatility technology and lower supply voltages); (3) The Cost wall as the cost per device via pure geometric scaling of process technology is plateauing. All of these have led to the slowdown of the traditional device scaling.  In order for computing systems to continue delivering sustainable benefits for the foreseeable future, alternative computing architectures and paradigms have to be explored in conjunction with emerging device technologies.
