本文揭示具有内存封装堆栈下之控制器之内存设备及相关之系统及方法。在一实施例中，一内存设备经组态以耦合至一主机且可包含一基板、内存封装之一堆栈及定位于该堆栈与该基板之间之一控制器。该控制器可基于来自该主机之命令而管理由该等内存封装存储之数据。

Memory devices with controllers under stacks of memory packages and associated systems and methods are disclosed herein. In one embodiment, a memory device is configured to couple to a host and can include a substrate, a stack of memory packages, and a controller positioned between the stack and the substrate. The controller can manage data stored by the memory packages based on commands from the host.
