Abstract
A high density memory module in which memory chips are mounted in an array of rows and columns on a printed circuit board. The circuit board includes groups of serpentine parallel conductors which extend along adjacent columns for connecting corresponding power, ground, control, address and data pins between the adjacent columns to one another. Adjacent groups of serpentine parallel conductors are nested within one another. According to the invention, high density packaging is provided for large chip arrays, using a minimum number to vias to interior board layers, and minimum interchip spacing.
