EXTRA HIGH BANDWIDTH MEMORY DIE STACK

摘要

A system includes a central processing unit (CPU); a memory device in communication with the CPU, and a direct memory access (DMA) controller in communication with the CPU and the memory device. The memory device includes a plurality of vertically stacked chips and a plurality of input/output (I/O) ports. Each of the I/O ports connected to at least one of the plurality of chips through a through silicon via. The DMA controller is configured to manage to transfer of data to and from the memory device.
