High density interconnect apparatus

A circuit board apparatus adapted to store large amounts of information in a densely packed configuration comprising:

• a circuit board;
• a plurality of information storage modules having a plurality of stacks of integrated circuit devices, each stack having a plurality of integrated each of said devices being electrically and mechanically connected to a plurality of edge boards which maintain said devices in said stacked relationship;
• retaining means attached to said circuit board for retaining said edge boards on said circuit board, said retaining means further comprising a memory metal portion forcing said retaining means into an open position in which said edge boards can be non-destructively removed from or inserted into said retaining means, said retaining means further being normally biased in a closed position in which an edge board is retained within said retaining means for connection to said circuit board;
• and
• connection means for electrically connecting said edge boards to said circuit board, said connection means further comprising a substantially flexible electrical connector electrically connecting said information storage modules and circuit board;
• whereby electrical communication between said modules and said circuit board can be performed.
