WebDRAM systems are hierarchically organized: Channel-Rank-Bank. A channel is connected to multiple ranks, and each rank has multiple banks. This hierarchical structure facilitates creating parallelisms in DRAM. The current DRAM architecture supports bank-level parallelism; as many rows as banks can be moved simultaneously at bank-level.
