Figure 7: The proposed Half-DRAM models with the timing illustration. (a) The logic view of Half-DRAM-1Row and Half-DRAM-2 Row (left) and the row/column control design for Half-DRAM-2Row; (b) Timing diagram to illustrate the relaxation of tFAW as well as the integration of sub-array level parallelism [10] for performance improvement.
