A 16-Kb 1T1C DRAM Supporting Conventional and Compute-in-Memory Access Modes

In this paper, we propose a 16-Kb 1T1C DRAM with compute-in-memory (CIM) access mode for applying in various DRAM-based CIM applications. Unlike conventional DRAM (CD) access mode, which accesses all 64-bit data in a row over several operation cycles, the CIM access mode can access all 64-bit data in a row in just one operation cycle. This DRAM model was designed using 28-nm CMOS technology. By using the CIM access mode, memory operation achieves 8x faster compute speeds than that in CD access mode.
