A microelectronic package (10) may have a plurality of terminals (36) disposed at a face (32) thereof which are configured for connection to at least one external component, e.g., a circuit panel (70). First and second microelectronic elements (12), (14) can be affixed with packaging structure (30) therein. A first electrical connection (51A, 40A, 74A) can extend from a respective terminal (36A) of the package (10) to a corresponding contact (20A) on the first microelectronic element (12), and a second electrical connection (53A, 40B, 52A) can extend from the respective terminal (36A) to a corresponding contact (26A) on the second microelectronic element (14), the first and second connections being configured such that a respective signal carried by the first and second connections is subject to propagation delay of the same duration between the respective terminal (36A) and each of the corresponding contacts (20A, 26A) coupled thereto.
