IC Memory Cards Handbook, Page 2
The use of MB (Multi-Layer Bonding) technology means that the memory size
of the PC card can be expanded. (MB technology permits a mounting density 4
times that of conventional SOP mounting and twice that of TSOP mounting)
MB technology
This system achieves more than double the mounting density of conventional
methods by using the TAB system to bond the memory chips to the film carrier
and then stacking them on the printed Circuit board.
MB technology: structure of a stack of chips (1)
