Abstract
Disclosed is a three-dimensional circuit structure particularly useful in semiconductor memories. The circuit structure consists of a stack of modules mounted on a mother board with connectors between adjacent modules in the stack. The connectors mate with staggered and through terminals on the modules; the staggered terminals being used for circuits routed to destinations on specific modules and the through terminals for circuits routed to destinations on more than one module.
