Abstract
Embodiments of the invention may generally provide techniques that allow mapping of memory devices in a multi-chip package (MCP) to memory segments of an address space. For some embodiments, a multi-bit device ID, which corresponds to a memory segment to which that device is mapped, is loaded for each memory device. Higher order address bits are then compared to the device IDs assigned to each device. An internally generated chip select line is asserted for a device having a match between the address bits and its device ID.
