Abstract:

The development of non-conventional Von-Neumann architectures becomes essential for breakthrough computing in Internet of Things (IoT) devices. The main objective for IoT application is to lower as much as possible the power consumption to promote autonomy. The key to solve this challenge is to reduce the data transfer between memory and computing unit. As emerging non-volatile memories and especially resistive switching technologies (ReRAM) can today be co-integrated with CMOS on hybrid process, we propose in this paper to develop bitwise logic operations inside and close to the memory array. Using two transistors - one ReRAM (2T1R) memory cell architecture with differential approach to enhanced read reliability, we can perform logic operations without impacting the global memory architecture. Thanks to parallel data sensing, the structure enables fast computation of any bitwise logic operations (ID, AND, OR, XOR in their natural or complementary form) with high reliability, promoting the computing in memory (CiM) concept.
