Claim 19:
20. A microelectronic device, comprising:
at least two blocks, each of the blocks comprising:
a source region vertically interposed between a lower stack structure and an upper stack structure, the lower stack structure and the upper stack structure each comprising insulative structures vertically alternating with conductive structures, the source region comprising at least one conductive material comprising, along a lower surface thereof, an array of V-shaped extensions;
a lower pillar array extending through the lower stack structure;
an upper pillar array extending through the upper stack structure;
a lower drain region below the lower pillar array; and
an upper drain region above the upper pillar array;

a slit structure horizontally interposed between neighboring blocks of the at least two blocks; and
conductive bridge structures spanning the slit structure, from the source region of one of the neighboring blocks to the source region of another of the neighboring blocks.
