accordance with one embodiment each tile is capable of providing 8 inputs or outputs thus in such an example a plane is capable of 64 inputs and outputs each plane may have sensing circuits associated with a group of eight tiles in one embodiment a local input output may be provided to the various tiles of the plane thus referring to fig1 a series of tiles 13 making up a plane 12 may have a block of contiguous sensing circuits 14 the tiles 13 may be coupled to an 8 bit local input output line 16 thus the eight tiles may output a total of 64 bits if it is desired to have more outputs than is possible with one plane for example 128 bit outputs two planes may be paired to provide the desired number of inputs and outputs two planes that are grouped together may be collectively known as a partition referring to fig2 the planes 12 a and 12 b together could make up a partition similarly the planes 12 a and 12 c could make up a partition likewise the planes 12 b and 12 d could make up a partition each set of adjacent planes such as the planes 12 a and 12 b may share a block of physically contiguous sensing circuits 14 such as the circuit 14 a particularly in the case where the partition is made up of the planes 12 a and 12 c the sensing circuit 14 a may be shared between the planes 12 a and 12 b since these two planes are never accessed at the same time in other words by interleaving the planes in forming partitions by taking two non adjacent planes to make up a.
