, Memory Subsystem.
The POP device includes feedthroughs in addition to the GPMC and SDRC interfaces positioned at the
top of the package. There are several feedthroughs from the bottom ball-grid array (BGA) to the top (or
POP) interface to support different memory combinations.
The feedthroughs provide power to a top memory device or provide specific memory signals from the
bottom BGA to the POP interface.
NOTE:
It is possible to monitor the DDR SDRAM temperature if the memory multichip package
allows the temperature sensing option. A feedthrough is used to lower the
temperature-sensing dedicated signal to make a connection with a GPIO. For more
information about DDR SDRAM temperature-sensing management, see
, Memory
Subsystem, and
, General-Purpose Interface.
shows the implementation of feedthroughs on the POP and the different paths between the
bottom and top of the package.
