Memory module system and method

A circuit module comprised of:

• a flex circuit having a main body with first and second sides, said first side of the flex circuit having first and second sets of multiple circuit mounting areas on which are disposed integrated circuits of a first type which have a profile thickness of HM and the flex circuit exhibiting a perimeter defined by two opposing short sides (PEshort) and two opposing long sides (PElong) to manifest a configuration of approximately rectangular shape, the flex circuit having a peninsular area set off from the main body of the flex circuit by separations, said peninsular area not extending beyond the perimeter of the flex circuit and having on the first side of the flex circuit, a peninsular circuit mounting area having thereon disposed an integrated circuit of a second type having a profile thickness different than HM;
• a rigid substrate about which said flex circuit is folded to place both the integrated circuits of the first type disposed on the first and second multiple circuit mounting areas of the first side of the flex circuit adjacent to the rigid substrate and the integrated circuit of the second type mounted on the peninsular circuit mounting area.
