Memory module

A memory module for an electronic system, such as a personal computer or server, includes a double-sided, 184-pin, dual in-line memory module printed circuit board. A plurality of individual electronic components are mounted on both sides of the printed circuit board. Each electronic component includes an electronic component printed circuit board, a first pair of stacked memory dies electrically connected to the electronic component printed circuit board, a second pair of stacked memory dies electrically connected to the electronic component printed circuit board, and a thin small outline ball grid array package at least partially encapsulating the first and second pairs of stacked memory dies. Preferably, an insulator is disposed between each pair of stacked memory dies.
