| Abstract(in English) | A novel multicore DRAM architecture with an ultra high bandwidth and a large capacity is proposed for high throughput computing application. The proposed architecture uses three techniques; 1) 5-stage pipelined 16-DRAM cores, 2) an early bar write scheme for an 8-ns cycle array operation, 3) 16-Gbit/s I/O circuit on each 32 through-silicon-via pairs/DRAM core. We confirmed by the circuit simulation assuming 45-nm 1-Gbit chip that the proposed architecture achieves 1-Tbyte/s bandwidth with 19.5-W power consumption. The chip area is estimated to be 52 mm^2. |
