Memory module has secondary memory chips mounted over one of primary memory chips electrically connected to conductive pattern, so that primary memory chip mounted below secondary memory chip is disabled

摘要

The memory chips (107,109) are mounted over one of the memory chips (105) that are mounted on a substrate (101) and electrically connected to an external terminal through a conductive pattern (111), so that the memory chip (105) mounted below the memory chip (109) is disabled.
