Abstract

A combined semiconductor device package includes a first semiconductor device package having a first semiconductor chip housed within a first enclosure, and a first substrate coupled to the first enclosure. The first substrate includes first solder balls and second solder balls, each in electrical communication with the first semiconductor chip. The first semiconductor device further includes conductive pads directly coupled to the first substrate. The conductive pads are in electrical communication with the first and second solder balls. The combined semiconductor device package further includes a second semiconductor device package having a second semiconductor chip housed within a second enclosure, and third solder balls in electrical communication with the second semiconductor chip, and coupled to the conductive pads of the first semiconductor device package. The combined semiconductor device package may be used for packaging a memory device that allows for increased memory package without increasing the package form factor.
