Abstract
An interconnected stack of one or more Dynamic Random Access Memory (DRAM) die also has one or more custom logic, controller, or processor die. The custom die(s) of the stack include direct channel interfaces that allow direct access to memory regions on one or more DRAMs in the stack. The direct channels are time-division multiplexed such that each DRAM die is associated with a time slot on a direct channel. The custom die configures a first DRAM die to read a block of data and transmit it via the direct channel using a time slot that is assigned to a second DRAM die. The custom die also configures the second memory device to receive the first block of data in its assigned time slot and write the block of data.
