A memory device includes a first string driver circuit and a second string driver circuit that are disposed laterally adjacent to each other in a length direction of a memory subsystem. The first and the second string driver circuits are disposed in an interleaved layout configuration such that the first connections of the first string driver are offset from the second connections of the second string driver in a width direction. For a same effective distance between the corresponding opposing first and second connections, a first pitch length corresponding to the interleaved layout configuration of the first and second string drivers is less by a predetermined reduction amount than a second pitch length between the first and second string drivers when disposed in a non-interleaved layout configuration in which each of the first connections is in-line with the corresponding second connection.
