ABSTRACT:
A decoder circuit selectively controls the transfer gate group. The transfer gate group is stacked so as to form a tree structure having multiple stages of transfer gates and enable a monitoring bus line to be connected to any column in a memory cell array. This configuration enables the current in each memory cell to be monitored at an external pad via a single bus line, which reduces the area occupied by the bus lines, suppressing an increase in the chip size.
