Patent ID: 7324352

Claim:
A circuit module comprising: a flexible circuit having a plurality of connector contacts, a first major side and a second major side, the flex circuit having two or more rows of surface mount arrays on the first major side and two or more rows of surface mount arrays on the second major side, the flexible circuit having a bend between a selected two of the two or more rows of surface mount arrays on the second major side, the second major side facing inward to the bend; a first plurality of CSP memory devices populated along the two or more rows of surface mount arrays of the first major side; first and second DIMM registers populated along the first major side of flexible circuit, the first DIMM register interconnected with selected ones of the first plurality of CSP memory devices to form a first DIMM instantiation, the second DIMM register interconnected with selected ones of the first plurality CSP memory devices to form a second DIMM instantiation; a second plurality of CSP memory devices populated along the two or more rows of surface mount arrays of the second major side, each of the second plurality of CSP memory devices having a top major surface; third and fourth DIMM registers populated along the second major side of flexible circuit, the third DIMM register interconnected with selected ones of the second plurality of CSP memory devices to form a third DIMM instantiation, the fourth DIMM register interconnected with selected ones of the CSP memory devices to form a fourth DIMM instantiation; a support substrate partially within the bend.
