US Patent 7046538 Memory stacking system and method

A method of forming a stacked memory module from a plurality of memory devices is provided. Each of the plurality of memory devices is modified to include a logic block for decoding a plurality of chip select signals. A first high density memory module is also provided that includes the modified memory devices and a serial presence detect device. The first high density memory module is included within an electronic system. Also, an additional method of forming a stacked memory module is provided, the method requiring modification of an address buffer to include a logic block for decoding a plurality of chip select signals. A second high density memory module is also provided that includes the modified address buffer and a serial presence detect device. The second high density memory module is included within an electronic system.
