Claim 0:
1. A circuit comprising:
a plurality of NAND blocks with corresponding block source lines, a particular NAND block in the plurality of NAND blocks including a block of NAND strings disposed between a multi-member set of bit lines and the corresponding block source line of the particular block; and
an input circuit to apply at least two different input signals to the multi-member set of bit lines coupled to the plurality of NAND blocks; and
current sensing circuits coupled to the block source lines, the current sensing circuits sensing a sum-of-currents, from multiple NAND strings, on the block source line in a selected NAND block from the set of bit lines through the block of NAND strings in the selected NAND block and producing an output derived from the current on the block source line, the current sensing circuits comprising at least one current sense amplifier connected directly to the block source line.
