Abstract
An aspect includes receiving a request to write data to a memory that includes a stack of memory devices, each of the memory devices communicatively coupled to at least one other of the memory devices in the stack via a through silicon via (TSV). The write request is received by a hypervisor from an application executing on a virtual machine managed by the hypervisor. In response to receiving the request a latency requirement of accesses to the write data is determined. A physical location on a memory device in the stack of memory devices is assigned to the write data based at least in part on the latency requirement and a position of the memory device in the stack of memory devices. A write command that includes the physical location and the write data is sent to a memory controller.
