Abstract:
A close proximity memory arrangement maintains a point to point association between DQs, or data lines, to DRAM modules employs a clockless state machine on a DRAM side of the memory controller-DRAM interface such that a single FIFO on the memory controller side synchronizes or orders the DRAM fetch results. Addition of a row address (ROW-ADD) and column address (COL-ADD) strobe reducing latency and power demands. Close proximity point to point DRAM interfaces render the DRAM side FIFO redundant in interfaces such as direct stacked 3D DRAMs on top of the logic die hosting the memory controller. The close proximity point to point arrangement eliminates the DRAM internal FIFO and latency scheme, resulting in just the memory controller internal clock domain crossing FIFOs.
