Abstract
A microelectronic unit includes microelectronic elements having memory storage arrays. First terminals and second terminals at a surface of the microelectronic unit are configured for connection with corresponding first and second sets of circuit panel contacts which are coupled with conductors of a common signaling bus on the circuit panel. Front surfaces of first and second microelectronic elements define a plurality of first planes at a substantial angle to a second plane defined by the major surface of the circuit panel. Each of a plurality of delay elements within the microelectronic unit is electrically coupled with a signaling path of the common signaling bus between one of the first terminals and a corresponding second terminal. In such way, the delay elements may reduce adverse effects of additive signal energy reflected from the microelectronic packages back towards the common signaling bus.
