Abstract: Various embodiments disclose a controller to manage memory devices. In an exemplary method, signals are exchanged with a host processor to allow the host processor to communicate with multiple memory devices in a memory stack as a single device, regardless of an actual number of memory devices within the memory stack. Power is provided to a single one of the multiple memory devices in the memory stack at a time to reduce power consumption. Other methods, apparatuses, and devices are also disclosed.

Abstract: A single virtualized ECC NAND controller executes an ECC algorithm and manages a stack of NAND flash memories. The virtualized ECC NAND controller allows the host processor to drive the stack of flash memory devices as a single NAND chip while the controller redirects the data to the selected NAND memory device in the stack.
